Flinch Flex

When used as a Noun, "Flinch Flex" is the action when Person A quickly flexes their Arms and Trapezius Muscles and initiates an upper body lunge toward Person B, but quickly retracts the lunge, indicating they never really intended to actually grab, grapple or assault Person B.

The intention of this action is to cause Person B to react has though they were being attacked, and to protect or guard themselves, i.e. "Flinched". By the time they've done this, it has already been made clear that it was unnecessary to do so.

This act is intended to result in the embarrassment, shame or intimidation of Person B. It can be performed 1-on-1 between 2 people, where it is primarily used to intimidate Person B or to cause them to lose their confidence. Or it can be performed in front of a casual or intentional audience, where the goal is to embarrass Person B by tricking them into manifesting their fear or Person A.

It is considered very "macho" to be "Flinch Flexed" on (to be Person B) without flinching. Greater still to endure the maneuver without blinking or even moving your head (Total Badass).

Moves include many Dark type moves, and a few Ghost type and Normal type. Stomp, Body Slam, Astonish, Bite, Crunch...

A type of incident that should not be mentioned around the company of ladies, they suffer alot worse than men. a piss flinch is usually a drunken/stoned action performed (hopefully) in private when urinating. the 'piss flinch' is a desperate type of flinch involving the lower legs and hips simultaneously. a type of judder I suppose, resulting in a sparatic spray of piss over the floor to either side of the bowl/urinal, and occasionally into the stash of bog-roll if you happen to be at home. hmmm nice soggy piss cleaned arse hole for mother. With women, they can be catapulted feet into the air, of can be spun off the seat at a great velocity. this can result in serious injuries, and sometimes loss of rationality/piss (or both) - but these things are never discussed. I only know after extensive research. Piss flinch can also be used as a rather Facetious insult to a close friend, sometimes called neil, or Ning. this happy banter can soon digress into a slurry of vocal fumblings, and end in giggles of the funny type. yes, yes they can. can they? yes. is it? I think we all know.
