When one enters a chat room and watches for idiots, then, when the opportunity arises, tosses in a biting comment at very random times to humiliate the idiot.
So, I'm watching this guy Driss in chat, and he completely lied 5 minutes ago by stating something totally contradictory, so, I became a Chat Sniper and made fun of him.
