A type of hot box in which a bathroom shower is all the way hot on full blast to create a sauna out of the rest of the room. The extreme moisture build-up is known to absorb some of the smell, even though it can still reek on the outside.

When 2 or more males lay in an enclosed truck bed while smoking a minumum of one blunt per person. To be an official Mexican Hotbox, the truck must be a lowered Chevy S-10, and each blunt must be smoked end to end before lifting the cover.
Smoke poured out of the mexican hotbox when I lifted the cover, we smoked at least 4 blunts while we were in there.
