In a pit thread someone* told a poster that he was “cordially invited to sit on my dick and spin.” Still cracks me up.
*The post must have gotten culled when the old ones were removed, so no link.
“Is that a leg?”
Enough said.
“call bullshit”
“X-y Mc-Y-Y”
“23 kinds of crazy” (used in reference to Sharon Stone)
“SQUEE!”
I actually say this to people who say something I consider too off the wall:
“prehensile rectum”
That one came from thinksnow.
I’m sure I’ve picked up vocab, but the thing I miss most is this guy:
:dubious:
I have to keep him suppressed when in meetings.
I think I make that face A LOT while watching television commercials.
Some people have issues. She has a subscription.
Glurge was actually coined by the irrepressible **patch ** (Pat Chapin) from the UL mailing list. Ask Barbara Mikkelson, and she’ll confirm this.
This exclamation was from way back in 1999, but I don’t recall who said it:
"Chocolate Christ on a cookie cross!"
I thought it was hilarious and I’ve used it a few times, as well as asshat (which doesn’t sound as good spoken as I’d hoped), squee!, glurge, and bullshit meter.
I just picked up “douche-hawk” from another board, in reference to Sanjaya’s ponytail-mohawk from American Idol…but y’all can use it if you’d like. 
“Very vaguely creepy.”
It’s the perfect encapsulization of a common and familiar feeling, and it didn’t exist until the so-titled and now-classic thread.
(Anybody have a link? The search engine is being persnickety.)
Someone on this board once described the act of cleaning himself after a bowel movement as being like trying to get peanut butter out of carpet, and that phrase has never left me. Alas, neither has the image the phrase conjures up.
Well, thank you very much, Knead! I hadn’t seen that one. 
The word “fuckchop,” first used, I believe, bu jarbabyj (back when that was her username – I can’t remember what she goes by now).
Hey thanks!
My pleasure. One of the funnest things that ever happened to me online was one day when I Googled my SDMB user name and found (among scores of bad baking humor) a site where someone had listed some of their favorite quotes which included not one but two things I had said here.
I can never look at the word “Gotcha” in print without thinking “Gotcha ya!”
Not just the Duggar family – this has become my stock phrase for any pathologically prolific people. (Although it is stuck in my head as “It’s a vagina, lady, not a clown car.”)
I also use “Woohoo! I am masturbating like a motherfuck!” as a general expression of enthusiasm, although only amongst my closest friends.
With all due respect to Guin, I first heard that line from Dennis Miller.
I just cracked my forehead on the desk laughing at that one! I have no idea what the hell it means, but it’s a scream.
