Gainz Goonz
The gym people who think they're the best because they can lift more than you. They're loud, proud, and never shut up about their gains. They're like the kings of the gym, and you're just the peasants.
'The Gainz Goonz were flexing at me while I was still trying to do 10 push-ups.'
'I tried to be a Gainz Goonz. I got sore, I got tired, and I got laughed at.'
'The Gainz Goonz are like the royalty of the gym. I'm just the background noise.'
