Pinch, Punch, the First of the Month

A school playground rhyme, often exchanged between friends on the first day of a new calendar month. Pinch, punch, first of the month and no returns of any kind. It's sort of a good luck tradition or maybe just an excuse to punch someone in the arm. And if the other person goes, ah, a slap and a kick for being so quick, that's legal. But you can block it by saying a pinch, a punch for the first of the week with no returns - they don't have the right to kick you.
