Your 'Mean Girls' Dictionary: 17 Insults Gen-Y Girls Should Never Live Without

But let's not get too sappy, lest we forget that we also picked up some sweet, new and creative ways to insult people. Now, while we do not encourage these be used seriously, we thought it would be fun to break down a smattering of the film's biggest and best insults.
