Coolioolio

See coolio. It's meaning is the same of coolio, but this one is usually only used when something is EXTRA cool.

"Man, that lion just ate a LLAMA! Coolioolio yo!"

coolioolio, yo

Uber-cool, the pinnacle of coolness, with a hint of street.

Or

A very long way of saying "yes".

"Will Ferrell sure is coolioolio, yo!"

or

"Wanna get some frozen yoghurt or maybe a whole meal of food?"
"Coolioolio yo!"
