Zugzwang is a German word meaning 'compulsion to move'. In chess, it refers to a position where any move a player makes will result in a disadvantage. If it were legal to skip a turn, the player would do so, but since a move is mandatory, they must worsen their own position. This is most common in endgames.

Mutual zugzwang (also called reciprocal zugzwang or trébuchet) is a rare endgame position where whichever side moves loses. It's a favourite theme in composed studies.
