Just wondering,where exactly did this trope's name come from? I feel like it's a play on words or a pun or something, but I just don't get the joke.

The last sentence of this entry disturbs me, for reasons stated on the Unprovoked Pervert Payback discussion:

• Subverted in Minami-Ke when Natsuki, one of Touma's older brothers, gets pushed into Haruka resulting in a grab. Haruka knows perfectly well that it was accidental and does not hold it against Natsuki. However, the incident occurred in front of Haruka's class, so for the sake of appearances she still has to punch him out. To his credit, Natsuki puts his hands behind his back and takes it like a man.

I'm deleting it, just as on the other page.
