A person who you hang out to smoke weed. You don't need to be a
close friend or don't even need to get along with him/her. The reason you hang out with that person can vary but it is usually because that person buys the weed or is willing to
burn his
leaf and smoke it up with you.
Duke: Dude, who was that weird guy? You
two are not hanging together, are you?
Tobby: No!
Well, he's my weedster so yes we hang out
sometimes but he's not my buddy or something.
