Kabedon

Kabedon (壁ドン, lit. "wall bang"), or kabe-don, is the act of hitting a wall with the sound "don".

It is separated from two Japanese words, with kabe (壁) meaning "wall", and don (ドン) being the sound made when a strong force is applied to the wall. This term usually refers to romantic confessions between lovers.
