This word is like coolio, but it has a different meaning. I don't know what coolyo is. You can use it for anything-- it's one of those words. You can use it as a greeting, noun, a verb, or a screenname.
"Coolyo! 'Sup?!"

"That coolyo is a weirdo, totally."

"Dude, I'm gonna go coolyo!" ('Dude' looks at speaker oddly, perhaps with an eyebrow raised)

'Bla bla bla'
