Flying Mushroom Stamp

The act of forcing someone to kneel down (have them stand if they are much taller than you), then removing all your clothes, and getting to a good distance. Once you have achieved the desired distance, you then run and jump, swinging your hips causing the head of your penis to slap them in the face, leaving a bright red imprint shaped like a mushroom.

Please exercise extreme caution when performing the Flying Mushroom Stamp. Serious injury may (and often will) occur.

I performed the Flying Mushroom Stamp on that bitch, dawg!

mushroom stamp

This is when a guy hits a girl in the forehead with the tip of his penis.

Specifically, the bottom part of a circumcised penis looks like a mushroom head, so the male would tap the bottom tip of his dick on her forehead with his mushroom and thus stamping her forehead.

Typically performed on females that you feel are sluts to make them feel like a complete slut.

i hooked up with this slut so I mushroom stamped her, just to be an ass.
