The act of getting a blow job by someone's mom and right before you ejaculate you pull your schlong out and glaze the mom's face like a donut and then punch the mom in the side of the temple so hard that she passes out. That way you can deny the entire thing happened and say the bitch had amnesia if she tells on you.

Tom: That never happened cuz I HAWK PUNCHED the bitch.
Boomer: Then it did happen?
Tom: I just said I HAWK PUNCHED her so it NEVER HAPPENED dumb azz!!!
