verb- to jab someone in the butthole region while they aren't looking, often with the aim of causing them to make a mistake. Though generally performed with the thumb, gubbing can also be accomplished with a similarly blunt object, such as a summer sausage. Named for an elderly bowling alley pro-shop employee who invented the maneuver.
Gub just gubbed Josh and he missed the shot on the 8-ball!
