ok, this may sound dumb, but i was 13, and my best friend was 12 when we did it. we hated this one girl, and her whole group, and we wanted to destroy it, because we’re evil, and they were #*@!es. so basically what we did, was not talk #*@!, because then they would obviously know it was us.but we discouraged people from liking them, and made them out to be bad people (they were), and then, as time went on, we made ourselves seem more "popular" than them, to make them more insecure than they already were, by writing at least 5 noted to each other everyday, and making it out to be like thay were from different people as well as each other. also, we would pretend to be friends with certain people in that group, and we slowly turned them against the leader of their stupid little group. we eventually split apart the group, (also by stepping up our social activity by doing funner things than standing around talking about people, which is what they all did.damn morons.), but the thing that really got the leader in the end, was a certain note that we forged, and left in the "8th graders’ hallway". we didn’t like 3 different girls, so, what we did, was pretend to be one of those girls writing the note, to one of the other girls we didn’t like, about the third girl we didn’t like. we basically talked about one of the third girl’s secrets, which was suffing her bra. sounds dumb, but it was true. and so it was, and everyone fell for it, and still, two years later, sometimes i hear people talking about the time she got real embarassed because of a "random note left in the hallway"
ok.this is stupid.i don’t suggest girls to do this to girls.it’s evil.and bad. i was young and stupid, and didn’t realize that us girls need to stick together, and not be catty #*@!es to one another.

p.s. i aknowledge that this is extremely stupid, but we were in 7th grade, so that’s my excuse
