Get the Peaknuckler mug.
A complete wally of a person. An utter mushroom tip of a human. A total rod-end.
*An unknown guy strolls into the room. Seems a bit of a knob*

From the Dungeons and Daddies podcast, one of Paeden's favorite pastimes. To play, you hold a pea between your knuckles and punch someone as hard as you can without bursting the pea. Similar to bloody knuckles, except no blood.
Paeden: "I'm the best at peaknuckle."
Darryl: (pulls sunglasses down so nobody can see his proud dad tears) "Yes you are, son. Yes you are."

A two-player game somewhat resembling Ping-Pong and with an element of soccer; it involves using your knuckles (touching the ball with your fingertips is forbidden, just as using your hands is not allowed in soccer) to flick a dried pea or other small spherical object back and forth across a table.
Peaknuckle is okay for rainy days, but I find it kinda boring and stationary... I'd rather play an outdoor ball-sport like tennis, where you can really dash around and get some exercise.

Game where kids jump in pool to find a hidden stick.
One person hides a stick in pool. The other kids have their eyes closed. When the stick is hidden the other kids open their eyes and yell “peaknuckle” when they see the stick and jump in pool to retrieve it.
