This trope is when a character expresses their overwhelming frustration by banging their head (often repeatedly) against something nearby. Desks and walls are the most prevalent targets, but other hard surfaces or objects — such as telephone poles, nearby appliances, or trees — are also acceptable.
Most often seen in visual comedies, as doing this in Real Life could prove very painful. On the other hand, it can appear in more serious works, either to lighten the mood of a moment or to punctuate the gravity of the situation.
Compare and contrast with Face Fault, Face Palm, and Wall Slump (the non-violent variant, to say the least). Also contrast with the more serious Punch a Wall.

A frequent occurrence in NarutoFan Fiction. It has been rationalized that the use of the Shadow Clone Jutsu (Kage Bunshin no Jutsu) can defeat a Kage's greatest enemy: paperwork. When someone (usually Naruto) points this out to the Third Hokage (or any Kage for that matter), the common reaction is for him to bash his head on his desk repeatedly while muttering "stupid" every single time, usually because he's known that jutsu for decades and never realized that he could use it for paperwork.

He finally gets his chance when they go on a date to the radio studio, and he's chosen to participate in a trivia contest. He lets her take his place so that he can hear her give her name at the end, even though he is very upset to learn that not only was the trivia on a topic he knew very well (the meanings of names, of all things), but the prize money was triple what it normally would have been.

Popular YouTube vloggers Hank and John Green (known collaboratively by their channel name of VlogBrothers) sometimes do this in their videos to express dismay at the idiocy of the average internet user (see various You Fail ____Forever tropes) or other frustrations. Especially John has been known to do this from time to time. "Huaaaa—hh HEADDESK!" (after which he had a bruise, and had to end the video).

These, sadly, solve a fair amount of the customers' "problems".
