I fuckin' know!

A loud and proud way of saying you're absolutely certain, even if you're completely wrong. People who use it think they're cool, but they're just loud and annoying.

Used when someone is trying too hard to sound tough. It’s basically just a way to show off and make people roll their eyes.

A phrase used by people who think they’re the best at everything, even when they’re clearly not. It’s like they’re trying to shout their ignorance at you.

A big, loud way of saying you're wrong but you don't care. It’s the kind of thing people say when they’re too busy being loud to think.

Used by people who think they're really cool, but are actually just trying to sound cool. It's basically just a waste of breath.
