prove them wrong. move on and act like it doesn't bother you.. if they know gossiping bothers you they will continue to do it.. although it may bother you. acting like it doesn't might give you a chance for them to stop.
be like "what did you say i hear my name" then talk about and make sure they know they are being talked about then be like b***** i hear my name one more time from your mouth i will make sure you won't to talk anymore bye haha good luck
There are some really great answers here. I really have nothing to add, just to agree completely with those who said not to stoop to their levels. It really doesn't matter what you say or do, people are always going to talk. Don't add your name to the list of "ignorant immature idiots". As long as they are talking about you, they are letting somebody else alone. Those people they are talking to, will finally realize that they are doing the same thing to THEM when THEY leave the room.
Be confident and walk RIGHT up to them and get in their faces. "Don't tal stupid crap about me you freaken jerk, Or "hey did you wanna say something to me? Because I heard you talking crap/ sh** about me!"
Happily walk by with a big smile on your face and 'accidentally' nudge them. Probably would work best if you had a separate friend with you, and you could be having a great time with them in front of the rude ones. It will show that you don't give a @&£! About what they say :) remember - as long as you know who you are as a person, nothing else in the world matters X
Tell them to "add that you are one heck of a kisser too" & wink, walk away - head up high with a smile! Then every time you catch them staring, blow em a kiss & smile..... they'll soon hate it & stop. And if anyone wants to know what you're doing say "spreading some love, obviously their parents don't give them enough attention."
Say "Wow I'm finding out so many new things out about myself" or if you don't want to go the humorous way say " "I get that your insecure and tear people down to feel taller, but just know, that your not actually growing.
