The paycheck that you receive on the off period of paying rent, so it can be dedicated to fun ether than going towards rent.
I got my playcheck yesterday, I'm gonna be a high roller tonight.
The 3rd paycheck in a calendar month that is usually viewed as a freebie, so a person has fun with that check instead of paying bills. A playcheck only happens twice a year.
This Friday I am going on a shopping spree because this is my playcheck.
