Auto-Flexing

Auto-flexing is when a heavily muscled person or animal's muscles flex on their own as they move.

Kara's muscular thighs made waves as she walked across the room and I couldn't help but admire them. I would define what they did as auto-flexing.

Dude with a slim build who sees himself as more of a Scottiah adonis body god
Usually found peacocking around the floor for no reason

Half flex is when you or someone else does something flashy but it's half-assed or cheated in some way.
