Flatplating is the act of inserting a ceramic plate into the anal cavity, oriented in such a manner that the entrance into the rectum is widened to the diameter of the plate. This is done through the rotation of the plate so that the view from the anus sees just a circle approaching it. The activity can be done with a partner, but that is optional. When flatplating, you have to be white because only white people would do shit like that :).
Eugene: Ay yo I'm about to do some Flatplating at 8:00 PM tomorrow.
Percival: We're white.
A form of Digitalsplaining where the perpetrator dismisses any argument by comparing it to Flat Earth belief—a culturally accepted symbol of irrationality. The flatsplainer says “this is literally the Flat Earth of X” or “you sound like a Flat Earther,” regardless of whether the comparison is apt. The goal is to trigger an emotional association that bypasses rational engagement. By equating the target’s position with a universally ridiculed belief, the flatsplainer makes any further discussion seem absurd.
Example: “She proposed a novel interpretation of archaeological data; he replied ‘this is the Flat Earth of archaeology.’ Flatsplaining: using a rhetorical shortcut to avoid actual debate.”
