Top definition
A term used by sport tipping websites where the tipper elects a round of his/her choice to have their total points doubled for that particular round. For example, in a round of AFL there are 9 games. If a player elects a particular round to be used as their joker round and they get 5 games correct, their score will be doubled to 10.
Boxy: I can't believe I am already 5 points off the pace after round 1. I really thought that Essendon would get up over the Suns. Luckily I still have 3 joker rounds to play to stage a comeback.

Crafty: Use them wisely dead shit!
