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.

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