Mufflered Fellatio 

Breaking wind while performing a blow job

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.

McDuffle Shuffle 

The McDuffle Shuffle can be seen almost exclusively on the west side of Jacksonville Florida on McDuff Ave. The McDuffle Shuffle consists of standing on the corner with an incomprehensible sign, often attached to a tennis racket. A shuffler is often mistaken for a bum, but bums carry signs that make more sense.

A true Shuffler often offers extremely good song lyrics for sale (mostly rhyming) and plasters his windows with various batshit crazy rants.

Hey look at Jeff, he is down on the corner doin' the McDuffle Shuffle again.

Yup, he sure is, look at his sign, it says, "Munchausen by Jackass" what the fuck does that mean?

It means he is Crazier than a rathouse shit.

muffler monkey 

Someone who drives a compact car (most likely a Honda Civic or Acura Integra) that sports a variety of tacky looking aftermarket parts which are meant to add visual flare and improve the car's performance. The most notable feature is the car's huge muffler that looks like a coffee can, and makes it sound like a weedwacker. Other common bolt-ons include huge spoilers, body kits, hood scoops, gauges, window stickers and other decals, tinted windows, lowered suspension, bright colored paint job, etc. More often than not, these cars aren't even that fast and are usually driven by high-school kids.

The sound coming from that muffler monkey's car is really irritating.

MOBERTUCKY MUFFLER 

When you're going down on your girlfriend put your lips inside her pussy and blow as hard as you can until you hear the sounds of a Mobertucky Muffler.

I left the Wabash with that girl from South Park and gave her a Mobertucky Muffler behind a dumpster.
