The days of the month when your paycheck arrives on a Friday. Can mean both Casual Friday or Cash Friday.

Let's get wasted tonight, its cash fri. Wearing t-shirt and jeans today, who cares? It's cash fri.

Biz-cash-fri 

It's a shortened version of Business Casual Friday and it is when an office puts a policy in place where the workers can dress casual ie. jeans or shorts and t-shirt.

Did you see that guy who showed up on Biz-cash-fri wearing cargo shorts and a Hawaiian shirt?

Johnny Cash Friday

Any Friday you work when you were promised a the day off. You fell like you are in prison and listen to Johnny Cash prison songs all day.

The inverse of Bon Jovi Friday

They said this job would be four tens but now I'm working four tens and Johnny Cash Fridays!
