dummyhalf
A Dummyhalf is another word used to name position "Hooker" in either Rugby Union or Rugby League. The word Dummyhalf is frequently used in Australia's NRL competition (National Rugby League) and Junior RL comps. A Hooker/Dummyhalfs job is to pick up the ball and either take a run to hopefully gain meters or pass the ball to someone so they can have a run. Dummyhalfs/Hookers often pass the ball instead of taking a run because they are often smaller and or slimmer blokes.
Look at their Dummyhalf, he's tiny compared to the rest of the team.
