Just when Jarczok had finally gotten used to those "Jar Jar" taunts from wasted junior executives shuffling back to their suites upstairs, the Lohan ex and current Tila Tequila flame Semel is said to have uncorked the searing rejoinder, "Do you even know who I am, fucking idiot? ... Google me, you dumb fuck." Of course, he probably did just that, uncovering the definitive Semel cheat-sheet to which his name will now be linked forevermore — and which also stated that Semel's net worth is not nearly what her father Terry's wealth might imply.

In any case, the elder Semel won't be coming to his daughter's rescue as the guard seeks unspecified damages; her little Google stunt sent his Yahoo! shares plunging 12% in early trading. This one's coming right out of her inheritance.

But her recent detention in Vegas after a drunken, assaultive visit to Caesar's Palace is what really compelled our consideration here: Who is this Hebrew hellcat, anyway? After the jump, learn everything worth knowing about Semel's climb to sort-of fame.

I. KNOW YOUR SEMELS

Courtenay, 28, is one of three daughters born to billionaire ex-Warner Bros/Yahoo! chief Terry Semel and Jane Bovingdon Semel, a former secretary to Susan George. She attended the Loomis Chaffee School in Windsor, Conn., before abandoning education for... we don't know. This is a historical gap we have yet to fill in; suggestions are welcome.

Regardless, she's clearly been doing some philosophizing over the decades, culminating in the powerful declaration of principles held forth below:

II. KNOW HER CANON

Courtenay got her start in 1991, portraying the crucial role of "Bratty Kid" in the Bruce Willis flop Hudson Hawk. Her 2000 follow-up — the never-released indie thriller Sweetie Pie — is best known for a cast also including Paris Hilton, Whitestarr vocalist Cisco Adler and the offspring of Dustin Hoffman and Kelsey Grammer.

Her "break" (and all of ours, really, if we're being honest) came when she was cast alongside childhood friend Kourtney Kardashian, George Foreman III, Fabian Basabe, Brittny Gastineau, Shanna Ferrigno and other nepotism all-stars on the 2005 E! series Filthy Rich: Cattle Drive. The show featured Courtenay and Co. skipping the boilerplate South Beach coke getaways for a bit of reality-TV ranch-handery. Sadly, due in part to reasons listed below, it was not renewed for a second season.

III. KNOW HER ACCOLADES

Courtenay's otherworldly bitchy contribution to FR:CD was roundly commended by critics who cited her distinctive look ("like an overfed mutant chipmunk") and her performance as a "brattier, PMS’ing version of Haley Joel Osmond [sic]" — outmaneuvering even Basabe as the worst human being the show had to offer. Word is her father was happy with the performance in Hudson Hawk as well, but as of press time he has not responded to Defamer's requests for official comment.

IV. KNOW HER STYLE

Spoiled lipstick-lesbian chic, at once aggressively designed and thoroughly disposable — all spangles, trash, heels and hair.

V. KNOW HER LOVE LIFE

This is where it gets complicated. Courtenay has been very publicly attached to no fewer than three young women of varying celebrity since 2007, starting somewhat retroactively last winter with Lindsay Lohan. "Everyone thinks Samantha [Ronson] is Lindsay’s first lesbian love, but we were very passionate until her fear of being found out drove us apart," she was quoted as saying. "At the time she was terrified her career would be over if she revealed her sexual tendencies. But then Samantha came on to the scene and I was dropped.” That triangle was fleshed out a little more this week by our cousins at Gawker, who noted that Courtenay and Ronson both visited LiLo separately during her rehab residency.

Next came Johnson and Johnson heiress Casey Johnson, who made the gossip rounds last month after a canoodling binge with Courtney. Enter Tila Tequila, who showed up maybe a week ago? A couple weeks ago? Anyway, now they've found true love, as evidenced by the scorching red-carpet chemistry below:

Surely she must also have been some poor bastard's beard somewhere along the way; as always, your tips are welcome!

VI. KNOW HER EMPIRE

You mean besides her father's 10-figure net worth, divided four ways sometime in the next 15 to 20 years? Not so much. We guess she can always lobby for a Filthy Rich: Cattle Drive — The Complete Series DVD Box Set, even though Basabe probably has a 75/25 split written into his deal. He thinks of everything.

VII. KNOW YOUR FUN FACTS

· Has been a Kardashian family BFF since the age of 2.

· Intimate public displays of affection with Tila Tequila range from kissing to spoon-feeding ice cream in VIP areas.

· Reportedly drove off from this year's VH1 Rock Honors with Casey Johnson in a $160,000 Mercedes that wasn't theirs. They returned it a few minutes later.

Now, however, with Chris Albrecht well into his tenure as IMG boss — and with a $250 million mandate to develop content with talent including Tiger Woods and Gisele Bundchen— the pressure is on for Forstmann to do something a little more constructive than star-fuck his way around the roster.

Conveniently, Semel seems to need a project, and IMG is as good as any. Forstmann reportedly wants $3 billion, though — an "aggressive price" by most accounts; he picked IMG up for $750 million in 2004 and may fetch a little more than twice that if Semel can sort out a deal with Dubai International Capital, a government-owned holding company that also, last November, bought 3 percent of Sony for $1.5 billion. We're all for the deal, frankly — anything that gets Semel back on the scene (though his support for Israel might be a problem in a country to which Israelis can't even travel), particularly if it results in IMG client Elizabeth Hasselbeck trenchantly interviewing Gisele atop a man-made ski slope in some desert shopping megalith. Good luck, Terry!

A tipster sent us the oddly e.e. cummings-esque internal email from Yahoo cofounder Jerry Yang announcing the departure:

several months ago, terry initiated discussions with the board of directors about stepping down from the chairman role once the board was able to identify a successor. since then, i have worked closely with terry and the board to ensure an orderly transition. today, we announced that terry will leave the board and roy bostock, who has been a member of the board since '03, will assume terry's role as non-executive chairman.

i want to thank terry for his years of service and contributions to yahoo!. he's been a great partner and a true friend. out of appreciation for everything he's done for us, we're naming the entrance to our sunnyvale headquarters "semel drive." stay tuned for more info.
