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!
