WTF is a "riti" cause I'm annoyed?

I'm building a Critical Damage rune page for and it appear as "C**cal Damage" when I name it. Can someone tell me what the fuck a riti is? Tired of RIOT sensoring slang shit from other languages that has absolutely no meaning whatsoever in the United States of America!

I don't want a fucking "Cr**cal Damage" rune page, I want a "Critical Damage" rune page! [slayer-jinx-unamused]
