noun. A pot smoker. Similar to a flautist, guitarist, trombonist, etc, except that the cheebist's "instrument" of choice is a joint, pipe, bong, or any device used to smoke marijuana. Can be used either as a term of endearment or a mild insult.
1. Holy shit, I can't believe the size of the gravity bong rip you just took down! You are a world class cheebist, my friend.
