A handjob in which someone is jerked off through a velvet crown royal bag, a bag commonly used as a dice bag by dungeons and dragons players. The sex act its self is referencing an item from dnd called a handy haversack (basically a lesser bag of holding)
Frank: How was dnd last night?
Bill: Dude! Jenna gave me a Handy Haversack after the game was over!
Frank: Nice!
