Jump the couch
Posted by Abe on August 27, 2005
I believe this one is a fairly new one. From Maureen Down, via NYtimes.com "According to UrbanDictionary.com, "jump the couch" has now become slang for "a defining moment when you know someone has gone off the deep end. Inspired by Tom Cruise's recent behavior on 'Oprah.' Also see 'jump the shark.'"
