A very hard flex that has an effect on people so strong they could end up dazed and confused
Damn man, he hit us with a fat flex when he walked in with the Gucci sweater and got two girls at once.

Get the fat flex mug.
A high degree of flexitude. It can be forced or come naturally. Usually occurs during brunch.
Example 1

Person 1: Is she doing an fbf (fat brunch flex) today?
Person 2: I guess so. She's in that white sundress.
