When a girl is giving a guy head and right before busting a nut, he strikes down violently on her forhead with his penis ( you earn extra points for giving her the flying thumper) you have to get on a chair and jump off of it, giving the thumper extra force.
Hey man this girl was doming me up the other day and she was using too much teeth! so I gave her the thumper man, I saw her wearing a neck brace the next day man.
