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.

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.

Yap Mufflehat 

A large and foolish hat that when affixed to a dog’s head, succeeds in embarrassing the yapping canine thereby effectively causing a cessation in barking.

I bought my nextdoor neighbors, whom we refer to as the Noisetards, a charming Yap Mufflehat for their yappiest pooch and amazingly it seems to have silenced them all!
