dacchi haiyore!_nyaruko-san hasuta male trap

I would call this androgynous and not a trap because he's not technically cross-dressing.
Well, I had an argument on another website about it, and it seems that, for certain people, the simple fact that the character could look or act in a "feminine" way is enough to qualify him as a trap (even if he never crossdresses or anything).

I don't want to debate about it anymore, since that day. But about Hasuta's case, he has just an androgynous face and he's in love with Mahiro.
"As a rule of thumb, if you can correctly tell the gender with complete certainty from the thumbnail alone, it's not a trap."
I would've guessed this to be a girl had it not had the trap and male tags so I'd say they're feminine enough.
