a newer stupid slang word for the word cool. Usually used by only immature brats and fags. (Not to mention the beans)
Hector: Mi pene es muy grande.
Chavez: Coolios!

1. Literally what it sounds like, but a more sarcastic version of itself. As a substitute for "cool", coolios can be used as a joke between friends or as a sarcastic response to something you don't really care all that much about.

2. An adjective, describing how cool and, in some cases, attractive someone else is. A gender-neutral word in this sense.
Example One:
John: Hey, I got the new game for my X-Box!
James: Coolios.

Example Two:
Abigail: Guess who I saw walking down the road today? It was Richard!
Amanda: Really?! He is SO coolios!
