assdent 

The giant indent left in the couch by one's posterior after an extended period of sitting. Often seen in conjunction with couch potato-itis.

The assdent your mom left behind after last night's episode of Desperate Housewives was so deep that we lost the remote, a half-eaten turkey burger, and someone's cat.
