Muchaco

The act of farting and accidentally shitting your pants. Your partner then licks your shitty underwear.

I had Taco Bueno last night and totally muchacoed. It was muy caliente!!

Muchaco Challenge

Order 5 beef Muchacos from Taco Bueno, and eat them all in 15 minutes.

It took longer for Johnny to throw up all the Muchacos than it did for him to complete the "Muchaco Challenge".
