Why do i get called whore ?

Okk so since its the end of they year people wanna start calling me a hoe just cause i hang out with alot of boys cause i make friends with them easier then girls cause all the girls i know start to much drama and i dont wanna be in it.. the clothes i wear are girly i guess i dont know i wear skinny jeans gladiators skirts that are short and shirts that show cleavage but thats cause i like the clothes and know some girls are starting to call me a slut whore ***** and stuff and plus they messed up my jacket and wrote # 1 just cause i like someone they like. are they jealous do they got some issues
