This word originally was made by Rosalyn . It is a definition of something that is so cool it can’t even be described as the word cool.

A word used to describe people who try very hard to be 'cool' and often make themselves look like a right nonce. A wannabe Coolio is someone who attempts to be like this and follows all the rules of coolioism but just can't be taken seriously at all.

Coolios tend to:
- Take selfies every fucking day with just their eye in the picture with some bent as quote as the caption
- Hang around together by the lockers, generally sit on the floor and text each other.

- Comment fire emojis on other people's pictures and ask for 'rates'
- Have 1 post on IG and 700+ followers
- Have some BS in their WEBSITE LINK because they're too cool to put it in the bio like everyone else
- Use duck faces
- Where print t-shirts
- Do cringe couple things on Social Media
- Follow other Coolios around although you're not wanted
- Think they're tough ad and hood but got breast fed until age 10
Lamar: Look at all them white Coolios vaping in that corner LMAO
Franklin: Wait Daw... Is that.. An Asian? HAHA WHAT A COOLIO!!
