It's hard to explain it properly, but for example: "you're bad" = you are bad and "you're spelling" = you are spelling. Well that still doesn't really make sense, but you're spelling or you are spelling doesnt make sense in proper English, his spelling belongs to him so its your and not you are :D, basically just use "you're" for anything which is "you are" and your for anything which isnt "you are".
Considering that English was my best subject in school, that I've been in both England and America for two weeks each and that I've dated an American for half a year I'm confident I'd get what you're trying to say if you made an actual effort.
They can be used as weapons
As in "I don't like the way you're spelling Element"
epic, and yes I got it
