How to get back at rude little kids?!?

i live in this sh*tty rust belt town with a population not very different from my college dorm. every few days, i go to town for the essentials like food, water, and vodka. unfortunately, it seems like you can’t go to town anymore without some stupid little urchins heckling you or something. there are a bunch of little ankle-biters that sit around the store entrance on their bikes. they har people doing absolutely nothing, and the little brats say crap to me such as "why are you wearing heels, lady? you must be a prostitute!" or "geez look at that dumb a** b*tch! (that's one of the tamer things they've said). i don't mind the teenagers as much, but i'm talking about the kids that are 9 - 10 years old! i mean, is it OK to tell some kid on a scooter eating a DumDum to f*ck off if he starts yelling sh*t? i’m just tired of my cigarette runs being marred by little redneck-spawn, and i’d appreciate your take on the etiquette of this situation. can i take their bikes? run them over?
