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!
