Fully dedicating your time and effort into unlocking an acheivement in a game to the point where you haven't showered in days and then sharing for everyone to see in a sort of bragging kind of way
You seen the new gun that just came out in COD? It literally just came out yesterday and my friend unlocked everything for it already. It was all over his social media. Major sweat flex.

A "Calvin Flex" is a braggadocious remark used when an individual has a lack of redeemable characteristics and has to rely on bragging about possessions and/or small achievements as a means to validate self-worth when receiving praise or the interest of others. Those who use such statements will often times be ignored or made fun of. This is due to the unwanted and awkward implementation of a"flex" used during a conversation. A "Calvin Flex" is often used when having a conversation with a woman who has a physical appearance rating between 2/10 - 10/10 (beggars can't be choosers).
Girl: Hey, let's go out to eat!

Girl: Wow, nice "Calvin Flex"
Boy: I made bread.

When a man gives himself a prostate orgasm and ejaculation by laying on his stomach and flexing his ass muscles up against his prostate to stimulate it. This can be done when the penis is either erect or flacid, and nothing needs to go inside your rectum. It's like bottoming solo.
Luke doesn't jerk off, he flexes off. Why can't you masturbate like everybody else does, Luke? Why do you have to figure out ways to have better orgasms and keep this shit a secret, Luke? I want to flex off too. Wow I bet Luke is great in bed, he knows all kinds of secret tricks.
