The term "hat trick" originated in cricket in the 19th Century. If a bowler took three wickets* on three consecutive tosses, they would stop the game and pass a hat among the fans, who were expected to toss a few coins in the hat as the bowler's reward.

The practice bled over into hockey about 30 years later.

* In cricket, taking a batsman's wicket is the same as striking him out, only it's done with just a single pitch by knocking the bail off the top of the stumps. From a scoring standpoint, taking three wickets in three tosses would be the same as striking out the first three batters in an inning buy throwing nothing but unhit strikes.
