$100 says it's just some innocent new preteen kid who made an anus joke and Stanley Richards has got us all worked up and practicing cyber bullying.
i get the whole teen ending thing but in terms of majorioty in an age I find it easier to consider 13 year olds as preteen
Quick summary: 12 and under is a pre-teen because if you can't figure that out after dissecting the word pre-teen then there is little hope for you, but we're going to consider 13 pre-teen because it allows us to be condescending and generally mean towards you because of your age. So in conclusion, welcome to RU. This is it. Enjoy your stay.
Although if you want, you could become Devon's Bitch #2 and I can protect you from all the evil, vile people here on RomU. EDIT: On second thought, I should make it clear I'm kidding. New Members should be treated well by default. Brofist.
The people I know who consider thirteen preteen say it depends how long you've been thirteen. I know, good for them...there it is. You can't say it's wrong of them to say that, though, just because "pre" means "before". Anything with a definition other than the conventional one could be slang.
