trou-down 

When visiting a nightclub or other such dancing establishment, the act of unbuckling one's belt, loosening ones trousers and allowing them to drop to the floor, continuing to dance with them shuffling around one's ankles. Often whilst inebriated.

"Did you see Simon the other night? He was dancing around those women Trou-Down, and they were loving it."
