Playable race in Warhammer 40k, the Orks are green-skinned fungus-based alien life forms who are completely obsessed with fighting, much like football hooligans in England, yelling "Waaagh!" as their battle cry. Notable for using the onomatopoeia "dakka" to describe the sound their beloved fully-automatic firearms make when firing continuously.
”More Dakka!!”, an internet meme meaning something like "more firepower!!", originates from the tabletop game.
