package jacker
A guy who can't stop jerking off so much his dong has stretched like a rubber band that's been snapped a thousand times.
My neighbor is a package jacker. He jerks off so much his pants are always falling down.
I saw him in the park doing his thing. He looked like he was trying to break the world record for solo sex.
He told me he can't stop because his brain is stuck on auto-porn mode.
