When you are playing Monopoly and someone takes one of every colored property to block you from getting Monopolies and winning the game.
Thanks again Dan and Garrett for Monopblocking me, AGAIN.

Dude, can you believe for the second game in a row that they are monopblocking everyone again. I might as well go bankrupt and give all my properties to Mr. David Volumns.
