A male that joins a beer club, only in the month of October, in order to receive weekly discounts on "award winning" cask-conditioned ales. This individual talks loudly, tells the same jokes each night, makes it impossible for a woman to sit at the bar in peace, might carry a man purse/fanny pack/satchel or book bag and is an "all nighter."

Literally everyone, ever. Including the writer of this definition.
