Sick day

An excuse to head to the beach and surf.

Damn, I'm supposed to head to work today and the surf is prime. I better call into work and take a sick day.

Sick boy 

The baddest of the bad, the coolest of the cool. Sick boy knife works blades are epic and a legendary masterpiece that Chuck Norris would be proud of.

You can cut down a tree with a sick boy knife and it's still sharp enough to slice up cow for steak dinner afterwards.

sick brag, bro 

A sarcastic, disingenuous expression indicating appreciation for another person's boast. Although "sick" usually modifies an expression with awesomeness, the "bro" effect is stronger, dominating and suppressing any notion of awesomeness.

Note: Not to be confused with "sick bag, bro", which mocks someone who brags about sleeping with an unattractive person.

John: Then he check-raised me allin. I realized immediately from the line he took that he was bluffing (likely a busted flush draw), so I called. He turned over the busted draw, and I won a huge pot! Isn't that awesome!?

Wally: Sick brag, bro.
