Past tense of gib; to castrate an animal, or in modern usage (gaming), to blow apart or fragment something.
From the noun 'gib' (a castrated cat or an older term for a castrated animal), possibly from a proper name 'Gilbert.' In modern gaming, it refers to the graphical effect of body parts separating.
The word 'gib' had a quiet, boring meaning for centuries—castration of animals—but video games completely revived it as slang for violent explosion effects, which is a funny example of how gaming culture creates language!
