Instagram flexing

When you make out with a beautiful chick just to show her off to your friends.

- Damn dog you kissed her for a minute and you flex the hell of out her instagram.

- yeah that was the point you fool but don't tell anyone

- don't worry, she'll never know, I'll make out with her two more times I guess

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.

Fart, pass gas or rip ass

My wife and I were snuggled closely on the couch watching The Notebook, when suddenly she did a colon flex, which confirmed she had eaten eggs for dinner.
