I dont Knwo - A person who tries to be cool but can’t spell ‘I don’t Know’

A person who tries to be cool but can’t spell ‘I don’t Know’ and just says it like it’s a swear word.

I don’t Know, bro. It’s just life.

I don’t Know, but I’ll curse you for it.

I don’t Know, but I’ll say it like I mean it.
