Mexican Breath 

Inhaling steam from a hot pocket, and exhaling it, imitading the smellyness of stereotypical ghetto mexican's breath after eating a taco or burrito

See that guy going off on that mexican breath? Smells like Juan when he smashed his hoe.

Mexican breath mints 

Hot Tamales candy or the generic version thereof. Used by stoners to mask the smell of their pot breath, and to alleviate the munchies at the same time.

Bob: Do you think mom will smell the marijuana on my breath?

Mike: I don't know man, better take some Mexican breath mints to be safe.
