Portugese Gas Pedal 

When one is having sex in the missionary position and then, right before you ejaculate, you pull out then stand up and stomp on your partner's vagina repeatedly. While stomping, you spunk all over her breasts and face. This is all accomplished in one, fluid motion.

My girlfriend was being a bitch last night at dinner, so I gave her a Portugese gas pedal as a punishment. That'll teach her!

Portuguese Gas Pedal 

Invented in North Carolina by a non-Portuguese man, it is when you are having sex with a woman doggy style and when she reaches climax you pull out and kick her in the pussy.

"That bitch pissed me off the other night so I lured her into bed and gave her a Portuguese Gas Pedal."
