A game, wherein you blether (a Scottish word meaning to talk at length at a fast rate; ranting, hypothesising, narrating or speaking in some other manner, without necessarily making very much sense) just for a single minute; mainly designed by [truncated]

From BoardGameGeek:

In this game, you must use an increasing number of words within a 1-minute blether. You are rewarded by using more words and by impressing your fellow players, who judge & reward your performance relative to someone else. After everyone has blethered four times, the 2 players with the most cards have a final blether-off and everyone else communally determines the best bletherer.
