Volcano Strat
When you go in the corner of a room, butt-naked, and lean against it upside-down with your ass against the wall and your back curled against the floor. You then proceed to masturbate, and when you ejaculate, you shoot it into the air in a similar fashion as a volcanic eruption, sometimes into one's own mouth.
Aye man, just hit that Volcano Strat, feeling good.
