Have you ever accidentally called someone an "FF" or an "HP" in real life before

Haha, no, but I sometimes catch myself thinking it.

I also have used moderate hero, though, and people understand what I mean perfectly. I was actually talking to someone about Middle Ground Fallacy, and I said, "You know, a moderate hero! When in doubt at all or at the slightest sign of controversy, run to 'the center' and plant your banner there."
