Guys are mean to girls they like because they don't know how to express their feelings. They also want to cover up the fact that they might like a girl and they will be mean to her to try to stop suspicions. This doesn't always work and you can usually tell if a guy likes a girl because he will obsessivly try to be mean to her at all times and will usually go overboard on it.
Differs from guy to guy, however, most guys like nice girls.
Answer Maybe they find mean girls to be a challenge for them.
I like (nice) girls soo not all guys do, just find the right guy
No they like hot and sweet girls They usually like sweet, kind, hot girls so if your mean I would try not to be if I were you. but I guess some guys might like mean girls.

No it doesn't.
Most of guys likes beautiful girls but this doesn't mean they married them.
The girls are just jealous of you and the guys probably like you.
They like hurting your feelings
Sometimes they like them and others they just don't like them.
As you deduced, it's because they don't like them.
Some girls are awesome, and like guys for who they are, some girls like guys cause they're hot, and some jerky girls like guys for their money and their cars.
Do you mean Curvy/developed/healthy? Yes they do.
