From WIKIPEDIA:

A facepalm is a popular online expression referring to the physical gesture known more widely as "smiting one's brow" or "smiting one's forehead;" that is, striking one's own face in a display of exasperation. In Internet discussions, the term is used as an expression of embarrassment[1], frustration[1], disbelief, disgust or general woe.

May I inquire, what exasperates you KDP3?
