Sesh wizards are essentially Gods of sessions. They have progressed from passing round a
single joint to taking stronger
drugs such as heroin, and are always looking to rope in some unknowing
people further down the sesh hierarchy into their illegal business. They are usually the leaders of the session as they are so experienced, sometimes abandoning parts of their life to further their addiction.
We don't say they're junkies, but they really are.
Person 1- Dude, there's a group of junkies taking
heroin behind that dumpster!
Person 2-
Don't call them that, they prefer to be called
sesh wizards.
