gib

/jib/

1. vi. To destroy utterly. Like frag, but much more violent and final. “There’s no trace left. You definitely gibbed that bug”.

2. n. Remnants after total obliteration.

Popilarized by id software in the game Quake, but actually goes back to an earlier game called Rise of the Triad. It’s short for giblets (thus pronounced “jib”), and referred to the bloody remains of slain opponents. Eventually the word was verbed, and leaked into general usage afterward.
