Gym budgie

Gym Budgie (noun):

A gym-goer who spends more time admiring their own reflection than actually working out. Just like a budgerigar parrot obsessing over its own image in a mirror, the Gym Budgie flexes, adjusts their tank top, and checks every possible angle—because gains don’t count unless they’re seen. Often spotted near the dumbbell rack, striking poses between sets of mirror curls.

“Bro, did you even lift, or are you just here for a staring contest with yourself?”
“Nah, he’s a total Gym Budgie.”
