Meaning: The accomplishment of three successes or wins.
xample: Pam has pulled off a hat trick, three divorces, three big settlements.
Origin: "Hat trick" originated from the English game of Cricket. The term originally referred to a bowler retiring three consecutive batsman with three consecutive balls.
This is roughly equivalent to a pitcher in baseball striking out three consecutive batters using only three pitches to each! This was considered quite an accomplishment and was traditionally rewarded with a hat.
The term is now used for other sports, always referring to an accomplishment of three. A popular use today is three goals by a single player in one game of hockey or soccer.
Comes from the days when it was common for men (and women for that manner) to wear hats to social events, and in Canada a hockey game is a social event. If a player scored three goals in one game, appreciative fans would throw their hats onto the ice.
