Ugh why do my friends always do this to me?

Like i hate how i'd be hanging out with my friends and then when a guy walks by, they'd be like shouting "Oh HEy she likes you" or oH hey she needs a boyfriend. Like yesterday i was just chilling with everybody and now my friend saw some old guy pass and he was like ohhh you look this girl said you're sexyy thats why her legs are open" and then the guy was like "oh she can't handle me". Like they do this all the time i'm out. Like once my friend really called this guy with mad tattos and he looked like someone you don't wanna mess with and he told him that i said he looks messed up.And then the guy got angry and started yelling at all 6 of us. Like why they do this to me? Ughh
