PUNCHKIN

When a girl is giving a guy a really good blow job, and after a few minutes into it she stops and punches him as hard as she can in the balls.
Or...
Tell a guy you want to give him a blow job, after he pulls down his pants wait a few seconds and give him a SUPER punch to the balls.

My boyfriend wouldn't stop playing video games so I gave him a punchkin.
