When you turn your window a/c unit on and shut the windows and the door so that one segment of your apartment is nice and frosty, while the rest is a million degrees and muggy because that’s how hot it is outside. Then you never leave that room.
It was so hot yesterday that I couldn't even leave my apartment - I just coldboxed my bedroom instead.

When you get in a car and do things you would do in a hotbox, like listen to music, however no drugs are involved
