How do you get back at a little sister that kissed your ex-boyfriend?

i need a prank to pull on her with getting caught by the rents, any ideas?How do you get back at a little sister that kissed your ex-boyfriend?
Tell her you heard the other day that your ex has oral herpes...and that you';re really glad it's been so long since you kissed him...cause you looked it up on the Net and anyone who kissed him recently is bound to get it.





And then describe to her all the horrible sores and pustules that will appear on the lips of those infected.





And how it never goes away.





And they have to tell everyone they have sex with as its a notifiable disease.





lol





That ought to keep her up nights.





And it's not the sort of worry she'll go to mum and dad with now is it?How do you get back at a little sister that kissed your ex-boyfriend?
1. Get an adult whom your parents do not know to call your home when your parents will most likely answer.





2. Then when your parents answer have the adult introduce themselves as working for the cities health clinic and they have the pregnancy test results in for your lil sis.





Works like a charm. All you have to do at that point is sit back and watch the fun.
let it go. its just a kiss and this was your ex-boyfriend. when you chose to leave someone or terminate a relationship its over. that person has the freedom and choice to go with and see anyone they want including your sister. youre too young to get wrapped up in this man stuff. they are like streetcars... a new one comes by every 5 mins.
As the first answer said, if he's your ex why do you care? Your sister was probably trying to annoy you so let it go, if you get ''back at'' your sister then she will do the same over and over again till you stop anyway, show her that it hasn't meant anything to you and that you don't care.
OMG! Your sister is a total SKANK! How could she do that? You should sleep with her bf or just let him have a feel or something dirty and trampy and then she will be sooo jealous she won't be able to stand it. She totally deserves it if you ask me! She's a pig!!!!
She kissed your EX boyfriend. How about you not be so incredibly possessive of someone you're not even going out with and actually wish your sister well?
If she has an ex-boyfriend do something to him that will get her really mad and then tell her that it is pay back for what she did to your ex-boyfriend.
I HAVE A SISTER THAT'S DONE THE SAME THING TO ME.YOU DON'T GET BACK AT THEM YOU JUST LET IT GO.FAMILY COMES FIRST YOU WILL LEARN TO GET OVER IT I DID
If he is your ex boyfriend he can kiss anyone he chooses to kiss. Jealousy is childish at best
Subterfuge has a brilliant idea!


You really should do that.
