Flopping

The act of pretending an undesirable political outcome puts you in serious physical danger, for the pupose of portraying people with whom you disagree as inherently violent or uncivil.
Perfected by American lefists in the aftermath of the 2016 presedential election, most notably through gimmicks like wearing "safety pins" in public and social media ramblings.

Derives from the act known as "flopping" in basketball, where a player pretends to get hurt in order to have a fouled called against an opponent.

Person A: dude this safety pin thing is catching on.
Person B: Yup. The left really takes flopping to a whole new level.
