After a night of extreme drinking, you get up to take a shit. And it smells so bad that your eyes BURN.
"Steve, i could smell your mexican shit on the other side of the building... how fucked up did you get last night dude?"

The shits you get after eating a large amount of Mexican food. You can often feel the spicyness as it exits your ass.
"Chinga man, I ate 4 tacos and some salsa last night and now I got the Mexican shits! My asshole is on fire!!!!"
