Something the early-model PS3s get when there's too much going on in a game at once. (i.e. too many explosions) Beleived to be a graphics card or RAM problem.
This phenomenon causes the PS3 to freeze up, usually while you're building up an epic kill streak and getting tons of points in BFBC2. This freeze-up is indicated by the HDD access light no longer flashing.
Player: Yo what happened? You were dropping those bitches like flies just a minute ago and then you went offline.
Friend: Meh, my PS3 had a Pwnage Seizure and needed to be restarted.
