For the past few years, Urban Dictionary has proved to be a useful resource when a joke or reference goes over your head.  Need to know about the "angry pirate" or "the stranger"?  Urban Dictionary is your one stop shop to look up the filth that Webster's dictionary wouldn't touch with a ten-foot pole.

The gang at Manofest has compiled a pretty damned good list of the 30 funniest Urban Dictionary definitions.  Some of them are funny in and of themselves, and some are just funny because someone went through the trouble of defining a "suicide wank".  See for yourself right here.
