Jack Show
A Jack Show is when someone's arms are so big, they might as well be wearing sleeves made of meat.
My neighbor walked into the supermarket shirtless in the middle of winter. It was a Jack Show, and the store got a snowstorm from the chill.
My cousin flexed in the middle of a video call. It was a Jack Show, and my mom asked if he was hiding a pizza inside.
At the park, my dad did a full body stretch in front of a kid. It was a Jack Show, and the kid now thinks he’s a monster.
