Metaphorical Uses
From this card game use came metaphoric uses, e.g.:
- "The CEO needs this report in one hour. That trumps anything you're currently working on."
- "He trumped my ace" for "I thought that I had a winning advantage, but he brought along something to defeat it."
- "At the hotel I ordered fresh orange juice with my breakfast ... the waiter brought out a trump excuse that there was not an orange in town."
In general strategy, a trump card is the move one party can use to attain decisive victory. In this sense, a trump card can be a person, weapon, or the starting of a chain of events.
