Dear god, that was scary. For a second there, I honestly expected to open up the thread and find somebody posting their number there asking for tsunderes for "hot dates". I've coped with a lot of bullshit on this site, from plain, garden variety stupid to gender wars to the never ending worthlessness of the console wars, but dear god if something like that happened, it might well have been the last straw.
Anyway, seeming as most tsunderes don't have balls, I probably wouldn't count anyway. I can change mood in a second, from calm and kind to rabid and murderous, but that's more a short temper than anything else. Most of the time, I'm just default grumpy-but-friendly.
