Cosby'd 

To rape someone

I Cosby'd the fuck out of Mellisa last night.

Cosby Sweater 

The sexual act of eating Fruit Loops, Fruity Pebbles, Trix, and Boo Berry- or any other 'bright, colorful' breakfast cereals- and then vomitting the tacky, dazzling mixture onto your partners chest. The result should look similar to the incredible sweaters that Bill Cosby wore during his highly successful 1980's sitcom "The Cosby Show".

Nicole was overjoyed to receive "a Cosby Sweater" for her birthday.

Cosby life raft 

When you shit in a toilet but do not flush. You just leave it floating there for an extended period of time like a life raft. So this way the smell builds up and the only thing the next person to use the bathroom can think about is your shit.

I was going to shower but somebody left a Cosby life raft in there and I couldn't even go in the bathroom

cosby step-back 

The act of finding a female and pulling a James Harden like 3 point maneuver and splashing a roofie in her drink.

YO DID YOU HEAR THAT MARC PULLED A COSBY STEP-BACK ON KENZIE THE OTHER NIGHT.

Cosby Face

When out of pain or shock, your face contorts to the trademark features of Bill Cosby.

"Yeh man! When I kicked him in the balls, he totally cosby faced!"

At 5:36 of "Heavy Metal - Taarna - Loc Nar - (HQ) Part 1 " on youtube.com, you can see the kid CLEARLY is cosby facing.

Cosby Steamer

Warmer than a "Cosby Sweater" and more fashionable than the "Cleveland Steamer", the "Cosby Steamer" is for both experienced freaks and novice sadomasochists alike; but not the faint of heart. A Cosby Steamer requires one to defecate on a partner's chest after consuming a chromatically diverse meal, thereby enveloping them in a multicolored shit-sweater. It's da puddig!

Though we'd eaten it all, Sarah's sweet corn chili was too good not to share, so when her roommate came home we warmed her up with a hearty Cosby Steamer.

Cosby Alert

The sudden need to take a dump. Often randomly placed in a conversation.

Ray: Did you see that story on the news yesterday?
Stephen: Cosby Alert! Be right back!
