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 completely serious example in one The Joker's stories; he's been arrested and is going to trial, and the possibility of an insanity defence has (unsurprisingly) been raised by his attorney.

The Joker calmly slams his own face down on the table he's sitting at, sits up with his face covered in blood, and says "It's that easy."

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.

Implied at the end of the Doby Gillis story "Her Face Was Familiar, But...", in which Doby is constantly interrupted every time he tries to find out the name of the girl he started dating (she doesn't realize he hasn't learned her name, and he's too proud to come right out and ask). 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. He's still cheered up when he learns that her name is Mary Alice. Then, he takes her home and she gives the last line of the story:
"Why, you know perfectly well I didn't give my real name. Doby! Why are you beating your head against the wall?"

In Hell's Kitchen, repeatedly, when a chef kept messing up souffles told Gordon that he was going to try brushing sugar and cocoa powder around the rims of the ramekins to keep them from sticking.

Happens in many The Nostalgia Critic episodes, as he reviews in front of a desk. In particular, the beginning of his A Kid in King Arthur's Court review had him slamming his head into his desk in an attempt to forget what he just saw.

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