Mushroom Cloud

Powerful Voluminous Ejaculation.

Named as such because it shoots from the mushroom shaped penis head and often forms random shapes where it lands much like clouds do.

I hammered my girlfriends "Cockgarage" so hard that I shot my "Mushroom Cloud" all over her "Double Stuffed Oreo's"

When a bitch is polishing your knob, and you ram your member into the side of her cheeck (from the inside) hard enough to leave a bruise.
