What is All Rii?
Now what can that stand for? Hmmm..
Of course man, it's the slang/abbr form of "All right". It is especially used in a light hearted/sarcastic fashion when exhibiting positiveness/assertion.
White cop: I am gonna arrest you for no fuckin' reason.
Cool black dude: No you're not. I'll see u in anotha life dawg. Now you take care all rii?
