Clam baking
Also known as: Hot Box
What does "Clam baking" mean?
Hot boxing, or clam baking, 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 hotbox locations include cars or bathrooms, but more ambitious smokers may aim to hot box larger rooms.
Example usage:
Come down to the cellar with us later, we're clam baking tonight.
