do what i've done with crackhead trash... write an annon letter to the feds, and when i say "feds" i don't mean you're fucking gay ass local police. those fucks are about as useless as a runner without legs.
write a letter to your local fed agency and tell them she is selling to minors... selling what? meth or wtf ever sounds trigger happy enough ... add whatever other shit sounds right to her "wrap sheet," send that shit, sit back and watch.
or you could be less intense but prolong the situation by starting a rumor that she's a crack fiend. her family cooks the shit in draino containers. their house is crawling with cockroaches. that home is a ticking time bomb . shit you could tell the neighbors too. lol. write another annon letter and send it up and down the street. haha awesome. i love watching people react when they are compared to complete and utter trash. the smart ones are on point but the ignorant people fidget and squirm. and what is more disgusting than crack/meth heads? you could even start publicly calling her 'Gum-by.' "Hey Gum-by! Keep smoking that pipe and you'll be the champ!"
or you could beat some sense into her. maybe her parents didn't kick the shit out of her enough. you could just beat her to a state of humble ... have someone non related do it if you're worried ...
or don't listen to me. be passive aggressive.
as for me, i am a fucking vengeful asshole. 95% of the time i rock and am laid back. it takes hard core abuse/provocation. and i truly have a distaste for rednecks, yuppies... that sort of trash to begin with. if i had to deal with her, that cunt rag would be hurting and it wouldn't be short term pain either.
