Captain Flex

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
Throws out a random flex when a member of the opposite sex is around

Look at BB over there peacocking round those hoes, he is the real deal captain flex

Blindly flexing

It's flexing but the person doesn't exactly notice. You do though, it makes you feel bad about yourself, sometimes.

Lily: "Oh my gosh! My 2 Ipads couldn't work, so I brought 2 more. And remember when I was in 1st grade? I dissected a cow eye!"
Me: "That's cool, I guess. You also already said that story of dissecting a cow eye over 100 times, I don't want to hear it anymore."
Me (thoughts): "She's blindly flexing again . . . "

Erlenmeyer Flex

The equivalent of the modern-day term "flex", or as a verb, "flex-ing"; but with the intent of impressing fellow Chemists/Scientists/Students within said realms of academia or even mere hobbyists keeping the waters of "nerd culture" warm for all. One possible example could be a novel proposed synthesis for a specific analogue of an obscure compound -- would be a GigaChad level Erlenmeyer Flex and would almost certainly result in sexual intercourse (wearing the proper PPE, naturally)

The invention of the Erlenmeyer flask is perhaps the strongest Erlenmeyer flex the world has thus far seen - a true Science Sector Chad
