That god-awful 2007 movie with Lindsay Lohan. She played a stripper with one leg and one arm. And she had a twin that her dad stole from his mom's fetus.
The movie came out after she was charged for DUI and cocaine possession, making her a bigging laughingstock than she already was. Quite a feat.
"In the gory psychological thriller “I Know Who Killed Me,” Ms. Lohan plays a wealthy college student who writes fiction, excels at the piano and refuses to sleep with her boyfriend...(and also plays) a stripper with a crackhead mom. No prizes for guessing which performance is more believable."
--Jeanette Catsoulis, New York Times
One of the dozens of slang terms used by Beavis and Butt-head. Buttknocker could refer to
a)A homosexual, as anal sex is the only form of intercourse for gay men, or
b)An erection in somebody's ass, referring to pulling out and then tapping and wiping the semen on said ass.
Beavis: Shut up, Butt-head! I'm gonna play drums on your nads with my foot!
Butt-head: I'd like to see you try, buttknocker!
Beavis: Don't call me that, Butt-head! (Beavis kicks Butt-head in the testicles)
