Oh my god! Did you hear that Nick and Kim were couching last night, while Kim's mother was in the other room working?!

A new form of dancing, consisting of enough guys sitting on a couch, making them very close to each other, while a girl is taken (or forced) to the couch and laid across the guys. The guys move up and down with the beat of the music in almost a "hump" like action. More than one girl can be couching if desired, or if the couch is large enough.
