boob flex 

When a woman (usually with big breasts) can make them move at will. It can be extremely sexy, is often done as a party trick (or to try to seduce a guy) in a low-cut top, and hypnotizes all straight guys.

For some women, only the pec muscles move and the boobs jiggle a bit, but on the most impressive boob flexers, the entire breast can lift up and "wave" from the bottom. It can be done one breast at a time, both at the same time, or alternating.

Women in the 18-30 age group can often be seen boob flexing to music to keep the beat. Some can do the move extremely fast. Sometimes women do it subconsciously.

Boob flexing is more impressive than a guy flexing his pecs, especially when a woman's breasts are large. Big, perky breasts actually seem to be more easily flexed and in fact can often appear to defy gravity despite weighing several pounds.

It has become a very popular performance trick in the last decade, probably because a lot if women work out with weights these days. How it got into mainstream culture is debatable but it appears it was first seen on MTV in the Room Raiders" show in the early 2000s. It has also been seen around that time on the show "Blind Date". There are tons of youtube videos.

This move is often performed along with booty twerking. Most likely, the fact that so many women workout with weights as time goes on, has a lot to do with the fact that more and more women can flex their boobs at will.

Stealthie 

when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.

This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"

FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"

The grindset is a contemporary ideology of self-exploitation disguised as strength, deeply tied to the aesthetics of the “sigma male” and to new digital forms of patriarchy. It promotes the idea that human worth depends on productivity, economic success, absolute emotional control, and the ability to work endlessly, turning vulnerability, rest, community, and tenderness into signs of weakness. Beneath its rhetoric of discipline and power often lies a profound inability to relate healthily to pain, fragility, and human interdependence.
“That’s the grindset, brother. While weak men sleep and complain, sigma males stay disciplined, work in silence, suppress emotions, and build power while everyone else wastes time chasing comfort.”
