When a character is sitting on the back of another character. The other character may be laying on their front, or be on all fours. Sitting on another's back is often depicted as the "sitter" asserting dominance over their "chair", the character sitting on the other's back may be using their butt to pin or crush the other character.
Sitting on the other character's back may also show closeness, or be done to give a character doing push-ups an additional challenge of lifting the other character's body weight.
Note: Not to be confused with riding on back, when a character isn't simply sitting on a static "chair", but being given a ride, especially when the character being sat on is feral
