The sometimes unavoidable urge you have to sprint to the bathroom at warp speed to unleash an unholy, ungodly hurricane of gas and diarrea after eating mexican food.
Man, I ate the burrito at Rubio's and a 1/2 hourlater, I had a Mexplosion
The result of eating copious amounts of Taco bell while drinking cheap Tequila.
"Last night was insane! I mexsploded all over the bathroom." "Mexsplosion is the act of Taco Bell food and cheap Tequila exiting your rectum at a high uncontrollable rate."
