A gym show pony are usually newbies who try to act big and strong but they're actually clueless. They normally come in groups of 2 or 3, they spend their time gossiping talking about rainbows and unicorns and the guy/girl they met on the weekend, what they ate in the last couple days while glancing over their shoulder scanning others while they're working out. The usually do spot a few who they would like to compete with whether it's strength, endurance or what they're wearing. Gym Show Ponies waste their time by going from one machine to another only to do 5-10 reps on each one. They grunt while they deadlift to attract attention before slamming the barbell whilst giving their self claimed competitor a deadly affirmation that they're strong and try to beat that if you can. They proudly walk around as if they own the gym when in actual fact they look like they've got a dick stuck up their ass and they try to secretly wedge it out while they walk.
Selena is such a Gym Show Pony, all she does is watch other people and talk about her private life.

Kevin thinks his Mr hot shot. I died from laughter the moment I saw him leg press 100 pounds, I think he did 8 reps before he jumped off to catch his breath.
