When people use Russian letters to make their words look cooler. Its retarded. Because the words they write are pronounced completely differently then they think the words would... its gross, lol.
Я =/= R, no matter how much they look alike, morons. For starters, the first one is pronounce as "ya", not the same as R. And it doesn't make your ******* words look 'cute' or 'cool', just retarded.
