A masturbation position, primarily used in the shower to keep from slipping. One hand on the wall, the other hand.. well you know.
Dude, I was jacking off in the shower, and I had to do the Heisman Trophy because the tub was so slippery.
Euphemism for Semen, cum, jizz, ejaculate, spunk, scum, baby batter, etc.
If you're in bad mood and jerk off. You feel better. Because the "Liquid Evil" is out of you.
If you're receiving felatio, and you ejaculate on to the girl's (or guy's) face without warning. They get angry, because they got "Liquid Evil" on them.
