When an over zealous gym junkie is loving his workout so much he moans each time he lifts the weights.
-AT THE GYM-
Dean: " Hey Rhys, check out the dude in the corner haha"
*Dude in Corner*: "Urrrrrrgggghhhhhh"
Rhys: " Geez, sounds like hes having a Gymgasm, what a tool!"
The sound a man makes when he is lifting to much weight in the gym.
I thought someone died in the gym the otherday, but it was just Mike having a gymgasm.
