assmuffler 

an insult i invented. i don't really use it to mean anything in particular, but i guess an assmuffler could be a slur for a gay man. like he muffles asses with his dick?

my brother paul is a total assmuffler ?

Wadded up toilet paper used to muffle the sound of explosive gas and diarrhea

The walls of my trailer are thin, so when I have company over I have to use an Oklahoma Ass Muffler to stifle my bowel movement
