A mexican burrito is where a (wo)man shits out a log into a condom and freezes it. Then proceds to use the shitcicle as a dildo until thawed out.

A Mexican Burrito is when you are having anal sex and the chick shits on your dick, making your dick all shitty. You then give her a shit stache, literally.. you give her a mustache with the shit on your dick.
