Just walk away.
If they confront you, keep a blunt object on hand and smash those b*tches in the face. See how they talk/taunt to you after that.
Very easy. Most kids on the street are just aggressive and swing like idiots. Jab, move, jab, move, jab, move. If that's too hard go for a takedown.
If you can't fight then you either
1. Learn how to
2. Don't fight
Why do you care what they think/say?
Everytime I walk my dog there's these girls that yell tramp, *****, hoe && I havent talk to them in years && I still have my virgenity so im not a hoe. I just want to fight them already and get it over with.
