Jumping the couch - Wikipedia, the free encyclopedia

"Jumping the couch is a term coined in 2005, modeled after the term 'jumping the shark'. The term was coined by Urban Dictionary to describe when 'someone has gone off the deep end' and is a reference to the infamous couch-jumping scene by Tom Cruise on The Oprah Winfrey Show. The term is usually synonymous with a nervous breakdown.

The editors of the Historical Dictionary of American Slang chose the term as the 'slang term of the year' 2005. It was also chosen by the nonprofit group Global Language Monitor as one of its top phrases for the year." (loads of examples at link) Jumping the couch - Wikipedia, the free encyclopedia
