GBM

Short for "Ganked by mother". When your mom comes into your room while you're gaming and you'e not supposed to be and proceeds to scold you while you're entire voice party can hear you. Occurs typically in traditional indian households.

Raunak had to log off for the night after he got GBMed mid game, sucks that we have to play 4v5 now.
