"Laughing viciously to myself." A spin off of "LQTM - Laughing quietly to myself" to show dark intent or spite.

When people type lol, rarely are they laughing aloud for the whole world to hear, but merely smiling and laughing quietly to themselves, or in this case they are laughing viciously.

A polite term for shoving a lubricated probe into the Earth's hole to release gas.
