look up any word, like dirty sanchez:
 
1.
Burning diahrrea. Often the product of eating fast food from shitty mexacian restraunts. Even worse when you eat lots of extra hot sauce.

After a long night of drinking and eating jalepeno poppers, the next morning you wake up with explosive diarrhea that feels like fire shooting from your asshole
Emily had a great time last night, but this morning she suffered some major firerrhea and now her butthole is all red and puffy.

The painful, burning and often explosive, projectile poo that results from eating too much mexican food.
