Definition

A charmingly euphemistic way to describe hooking up with someone, making casual sex sound like an awkward collision of bodies in dim lighting. It strips all romance and mystery from the encounter while somehow making it funnier. The perfect phrase when you want to discuss intimacy without actually discussing intimacy.

Example Usage

Did you hear that Marcus and Jennifer were bumping uglies in the back seat at the concert?
