A big-butted, strong woman who attends the gym in full makeup including fake lashes and heavy contouring.
Today at the gym I saw several Gym Kardashians working their glutes on the machines without smudging a stroke of mascara.

People in the gym that think they're in great shape striking poses constantly in the mirror and or for selfie pictures. What's funny is when you try not to laugh when you witness them doing this.

a newbie obese person who pretends to love the gym and always boasts on how thin he or she used to be and how hard it is to for them to go to the gym nowadays.
Tony just got fatter and is always complaining about how hard it is for him to go to the gym and keeps showing off his old photos of when he used to be able to lift, all while sitting at a bar drinking beer. Tony is a gym bluff, he likes to say he goes to the gym but never really does and is always at the bar.

When you are working out and you have excessive moisture in your ass. Irritation from sweat in and around your buttocks.
I have the worst case of GYM ASS from working out today. Sitting at this desk gave me a case of Gym Ass.
