To
toke is the action of taking a hit of marijuana,
therefor, tokin up means to have a session of smoking marijuana. You can toke on a joint, or take a
bong toke, and from this comes the phrase "tokin up".
The three of us are tokin up before the movie tonight, so we can get our
mind right before it starts. I prefer bong
tokes, but since we will be doing in the car, it will be easier to
toke on a joint.
