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.
