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 combine "coldboxing" (shutting the doors and windows with the window a/c on to create a cold box/room) with "hotboxing" (shutting the doors and windows while everyone smokes pot so all the extra smoke is contained and inhaled). Cool times!
