Shy guy: I want to, but she's with all her friends, and that's kind of embarrassing.

Shy guy: Shit, I hate being in zugzwang!
The word is from the German and means "compulsion to move"
The term is most frequently used to describe a strategy in chess whereby one player is forced to make a move they do not wish to make. It is also used more generally to describe any comparable situation.
