I was about to get some of that fine ass pussy over there until Paul came up and started talking about Star Wars again, he's such a muffler.

A man who farts up his nose while auto-fellating himself usually for sexual pleasure, but sometimes by accident
Ricky is in his room mufflering. I can't believe he can suck his own cock and then farts in his own face to kick it up a level.

Dammit, I was sucking on a huge new cock last night. Everything was perfect, except I was a little bit drunk, and I broke wind right in the middle of it all. Thank god he was drunk too, and we made a joke and called it mufflered fellatio. We had great sex, but I was pretty embarrassed.
