Something which takes an unbearably long time to happen. Specially used in cases where the said something used to happen on a regular basis.

Inspired by Indian Cricketer Virat Kohli's drought of centuries after his 70th international ton.

Steve: Dude, do you have any idea why Joe isn't texting me nowadays? We used to talk all the time!

Kane: I think he's pulling a Number 71 on ya.
