Gymeny

A "Gymeny" is the person with whom you have an imaginary conflict (beef), even though you have never spoken to each other. The goal is to surpass and outperform this person at the gym at any cost.

Person A: Hey, my "Gymeny" is doing bench presses. Let's wait until he's done, and when he wants to remove his weights, we'll say, "Can you leave them on? It's a perfect warm-up weight."

Person B: But isn't that your max weight?

Person A: He needs to know I'm standing on business!
