Pumpfaking is when you pretend to have a weapon, normally a gun, around your waistband. Sticking your hand on your waist pretending to hold the grip of the weapon.

Normally used to threaten others around them or using it to scare someone that doesn’t know if they’ve got a gun or not.
Tyrone told the cops he was pumpfaking after someone had broken into his vehicle early that morning, trying to scare off the thief.

Tyrone was a felon so he was not allowed to own any firearms.
