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.

Get the Liquid Evil mug.
Either something incredibly sexual or just evil personified in a liquid.

The second one was what I meant in my definition for “second”.

Sorry.
Liquid evil—in both definitions it is 70% pure evil. 99% off, buy now.
