Girth Worm 

An incredibly thick penis. Because of the extreme thickness, there are no condoms that can contain this massively wide unit. In order to have intercourse, one must wiggle their dick like a worm for several minutes to burrow in even the loosest of vaginas.

Did you see Philip's girth worm? It was huge!
