When your farts make a noise other than the normal toot toot.

Initially created to fill a gaping hole in emoticons because there was no smiley for "gassy", thus ":) + /'\ " had to be used.
Please note, however: If your ass is truly making a clanging sound, you should seek immediate medical attention.

The mental illness of a drummer or percussionist. Causes the drummer to stare at a cowbell with desire to play it leading to a point where they play it at an inappropriate part in a song. People with MCD play the cowbell often as possible and it can get annoying after a while to some, but to most, it is entertaining.
"Did you hear John during practice today?"
"No what happened?"
"His Mad Cowbell Disease led to a corny drum fill and it threw everyone off. He needs to control himself."

A facebook user group whose purpose is the encouragement of facebook content and humor revolving around the satirical cowbell metaphor made popular in a Saturday Night Live skit. The SNL classic mocks Blue Oyster Cult members (played by Will Farrell, Chris Kattan, Horatio Sands and Jimmy Fallon) in the recording studio where they are laying down "Don't Fear The Reaper" with record producer, Bruce Dickenson (played by guest host, Christopher Walken) who advises the fellas that they are going to want that cowbell in their sound and the track could use a little more cowbell to an already "cowbell prevalent" song.

A (subliminal) tool used to politely suggest to your long lost pal to add some content to their facebook profile.

The classic request for more facebook content.

A facebook classic.
Glad to see you on facebook, here is a link to my favorite user group.

This group was made for you.
