Joker
A slang used while smoking marijuana. To joker, means to hit the pipe, bong, joint, anything that is being passed around, TWICE in your one turn. Sometimes it will be noticed and you may be called out on it. Other times, it will be noticed, and the same will be given for everyone else in the group. And sometimes, you can just get away with it, if it is your own weed.
