Grease fart 

A Grease fart is a nasty ass fart that is highly flammable. This fart is kind of like a shart. When u have a Grease fart lots of poop or shit comes out. The shit can be small or super small. Big shits rarely happen. Only after you eat Ethiopian food. Grease farts are impossible to miss. By that I mean they smell awful. Like a dead cat wrapped around a smelly puib cover scrotum bag. That shit is nasty! If you ever have a grease fart you should evacuate your house right as it happens. If inhaled, a grease fart can fill your lungs with a smell that is worse than anything in the world!

fart grease

Fart grease – The sticky, foul smelling substance that builds up in the crack of your ass. It’s made up of a concoction of feces, sweat, smegma and lint..

My roommate is so nasty. He picks his ass, waits a few seconds and looks to see if anyone is around, then sniffs the fart grease on his fingers.

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.

Greasefarting 

Greasefarting is the act of farting when the anal cavity is experiencing conditions such as "swamp ass." Generally, it results from a lack of cleanliness of the top of the ass crack down to the gooch(a.k.a. skin-bridge).

After a long day of hot, sweaty work and three bowls of chili, John unleashed his greasefarting ass upon the unsuspecting welfare mothers standing in line for government cheese.
