Concentrated THC (the chemical found in marijuana) stored in a disposable cartridge, usually attached to a battery, the youngsters call it a pen. Many teenagers hit these shit boxes daily and 90% of the time have no idea what they are inhaling or how it's going to give them some lung disease 15 years down the line. But alas hitting off your neighbors pen in class is chill.

A term used to reference cannabis/marijuana/weed.
