There is a translation error.

Sorry for the grammar (it's very funny to talk about an error of the translation when you can't speak a perfect english), but... If you go on your PC to this:

"Steam\steamapps\common\super meat boy\locdb"

You should get onto a file with the translations. They aren't complete, and you can't see them in-game. I guess that when the translation ends, we could see them. Anyway:

I check it. And I found some "bad" translations:

Jill: Pervert. Translated as "Pervert (man)", when she is a girl. It's normal because... on the game, Jill is like a man. On these languages, the adjectives could say the gender too.

(Spanish) "Pervertido" should be "Pervertida". Also:

(Italian) "Pervertito" and (Portuguese) "Tarado" sounds like male adjectives to me, I can't claim this.

So, please, Team Meat, tell the translators that Jill is a girl and they should change it.
