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.

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.

Feces left around the anus. The situation one finds oneself in when, having defecated, one finds that there is no toilet paper available.
I had a crap this morning, but there wasn't any bumwad, so I had to go all day with a rusty muffler.
