YMMV / Dwarf Fortress. 1  Anticlimax Boss: Forgotten beasts and titans made of fluid tend to be this, since they fall apart at the slightest touch. 2  Broken Base: The friendly teasing that occurs between tile users and ASCII users, or between those who prefer Adventure Mode to Fortress Mode, is occasionally mistaken for this.
In lending agreements, collateral is a borrower's pledge of specific property to a lender, to secure repayment of a loan.
A pledge is basically very serious formal promise. You can pledge allegiance to your country, you can pledge to keep a secret, and you can pledge a sum of money to a cause. Pledge can be used as both a noun and a verb. As a noun, it can be a solemn promise you've made. Or even the person who makes that promise, like the freshman pledges who take an oath to join a fraternity in college. As a verb, it describes the act of promising.
