Okay, they are not in every anime.

Okay, actually I like them.

But I must list other things then fanservice, or the whole book would be filled with this cliche so...

Everybody knows them.
In anime, manga and reallife, there are a lot of fangirls.

And the fangirls (or fangrells) always fangirl (fangrell) about Yaoi. (Okay me too...)

Uhm... maybe I should stop this before I blame myself?

Anyways, I like fangrells in anime, but not in so many anime, okay? Okay.

Bye.
