I'm certain it's going to blow over eventually. Sort of like "Spectacle Fighters". Never heard that catch on and be used today, Yahtzee will forget about it, and so will the parrots.
Though I think it's stupid, It would be nice if it was broadened a bit until the term can go die in a ditch and never be looked at again goes away. Remembering correctly it was for "Realistic Shooters" so COD, GOW, all those things (as far as I'm concerned Halo belongs too but whatever) are classified as it.
Note: Even IF he DID mean it seriously, It was only because people kept saying he doesn't like shooters.
