Why do girls do this to me..I hate it

Why are girls always like shouting or yelling at me when im walking past them on the street.. I fear they’ll make a nasty comment ,when I walk past and this is very true of girls in numbers of two or more Why do girls behave like this? Do you personally do this to other people walking on the street? Like yell at them and make them feel threatened( for girls especially), even if they haven’t done anything to upset you I think the reason some girls behave in this way is because I check them from a distance to see whether they are hostile( not in a sexual way, jsut to make sure they wether they would start yelling in my face and being hostile in this sense ..but these girls usually pick up on this Usually they are almost certainly hostile, if they are loud from afar..I mean if they seem to be fooling around amongst themselves, from a distance I just presume that the minute I walk past them they are going to say something nasty, so as I walk past them and try and avoid looking at them directly in their faces, but that doesn’t deter them from making those comments anyways.. What would girls who are complete strangers do to you@ guys, when you walk past them alone all by yourself?
