A lean boy is someone who drinks a lot of lean. By drinking a lot of lean, that person is a very relaxed and calm type of person. He enjoys chill music while sitting with their eyes crossed. Most people want to be a lean boy, but don't have any to drink.
Dude: Dude why are you always lean, what are you?
Lean Boy: I'm a Lean Boy dude, I am very lean
