When smoking marijuana with a group of people and you ask everyone if they want to "Mexican sweat" whatever you're smoking, (be it a pipe, joint, bong etc.) and if everyone agrees you take a hit BUT DO NOT EXHALE until the mary comes back to you.
Smoker #1: Let's mexican sweat this joint.

Smoker #2: Aight

Smoker #3: I can't hack the mexican sweat!
