I'm okay with some versions of Gap Moe, but it's got to be well executed. Others, like 'A dominant acting submissive', i'm dead against. Mostly because these terms have a more concrete meaning for me BDSM-wise, rather than the fast-and-loose definition used around these parts.
I'm a fan of, in moderation:
- Your classic Tsundere, male or female.
- Tough or cool guys/girls being softies deep down.
- Thin guys stuffing their face with food (Like Darker than Black).
- A stoic male/female character doing something wacky or cracking a joke.
- A totally feminine guy/girl suddenly turning tough, angry, and almost testosterone fuelled over something. Points for loss of cutesy voice, devil flames, and if the character in question is a motherly type like Kasumi Tendo talking smack like a WWF opponent.
It's not really a fetish, just kinda funny and/or cute. A great example for me is almost anything Kurisu Makise from Steins;Gate does (Particularly in the movie), or when Rintarou Okabe turns dead serious and emotional instead of wacky batshit scientist.
