Muffler backfire 

When a girl is giving you a blowjob, and while choking on your dick, she accidentally farts.

So my girl was choking on my cock, and had a little muffler backfire.

I think my girl had to shit, because while she was gagging on my cock, she kept hitting with a muffler backfire.

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.
