Hat Trick

No, this sadly has nothing to do with a magician making your baseball cap disappear.

I wish.

Though I have seen a hat trick on telly.

Meaning & Etymology
Basically, it's what happens when someone wins something three times in a row! It comes from cricket, from when a bowler takes three wickets in a row and (please confirm this) gets given a new hat.

My cricket knoweldge is sadly lacking.

Incidentally, a hat trick is a hat trick no matter what kind of headgear the person doing the hat trick is wearing.

Use in Normal Speech
"I'm just warning you, there's a serious risk of a hat trick today..."
