something you say to a person that bores you, but you want them to seem like you're actually interested in what they're saying.
Person 1:"hey did you know that plants go through photosynthesis? also they produce oxygen for us to breathe!"

A lamer way to say cool.

An event that is mild on the excitement scale.

*Never use it in a sarcastic way because it won't sound good. Awesome>Cool>Sick>Coolioes
A:I got a new book to read.
B: Coolioes.
Coolioes was used here because the event isn't very exciting.

A:I got a new game!
Cool was used here because the event was exciting enough.

Using "coolioes" in a sarcastic way
A:I got a new yak!

This is why we don't use coolioes in a sarcastic way, because when you say it sarcastically it sounds like a fat bird.
