Nukeball
From Tardis Wiki, the free Doctor Who reference
Nukeball was a favourite sport among a number of Judoon, but it was outlawed on their home planet so the population was not wiped out. Despite this, is was still played illegally and often a star system would explode which signified a Pyrrhic victory. (PROSE: The Coming of the Terraphiles)
- Its name suggests the use of nuclear weapons.
