Translate Board Game Rulebook Jargon Into Plain English

The rulebook defines the term using two other terms it has not defined yet, and now the whole table is stuck before the first turn. This explains the term in plain English, using a comparison to something familiar rather than rulebook language, with a quick example of it actually happening in play.

Explain {RULEBOOK_TERM} from {GAME_NAME} in one plain-English paragraph, as if explaining it to someone who has never played a hobby board game before. Use a comparison to something familiar rather than repeating the rulebook's own wording back, and give one short example of the term in play.
