first world flex

Also known as “rich people problems”, a “first world flex” is essentially a first world problem, but one that’s simultaneously boastful as well as whiny and arrogant.

“Yesterday Phil was complaining about how he didn’t know which camera he should look into on his new iPhone 11. I fucking hate him and his first world flexes.”

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.
