I went to McDonald's with that greasy fart Snookie where we drank 40s from brown bags (the manager lets us, Snookie blows him for the privilege) as we wolfed down Big Macs; we both had greasy farts for three days.

greasy bacon wiener

A freckled-faced friend of yours that's always so horny, but has no one to fuck. He cannot use his own computer at home for porn, so he asks if he can hangout with you just to take advantage of your own computer for his needs. Regardless if you're in the same room or not he'll begin to jack-off to porn, after turning the chair in the other direction so you can't see him, and get his bacon like grease jizz on everything afterwards.

Wow, I've heard he's a real greasy bacon wiener.
