Hot Box
Also known as: Clam Baking
What does "Hot Box" mean?
Hot boxing is the act of smoking cannabis in a small, enclosed space. This fills the space with smoke, resulting (in theory) in each breath getting you a little higher. Popular hot box locations include cars or bathrooms, but more ambitious smokers may aim to hotbox larger rooms.
Example usage:
When I was in college, it was pretty standard practice to hot box the bathroom.
