Grumper Bumper
When you are in a bad mood but your significant other wants to engage in sexual intercourse. This is called the grumper bumper because although you're not in the mood, who are you to turn down sex, so you push through with the grumper bumper?
My hoe ass bitch burned my toast, and thought she deserved this dick! She pissed me off so I gave her the grumper bumper.
