grrreat

1. Something the popular cereal children's character Tony the Tiger would say to describe his cereal, Frosted Flakes, and all of its spinoffs, (i.e. Turboz.)

2. A very sarcastic remark after something has gone terribly, terribly wrong.

1. Tony: "Frosted Flakes, they're grrreat!"

2. Girl: Well, I think I can safely say that was the worst sex I've ever had.

Guy: Oh. Grrreat.
