look up any word, like blumpkin:
A pronounced mushroom head (PMH) is identified by a glans (or penis head) that is characterized by a distinct mushroom shape with a circumference that is significantly larger than the penis shaft. PMH is thought to bring greater pleasure during intercourse to females because of the friction created by the mushroom-shaped head (in contrast to the pencil dick) on the clitoris.
What did his penis look like? It was beautiful, he had a very pronounced mushroom head (PMH).
