I understand perfectly. I was just pointing out that the players, who live outside the game, might not view it the same way. Hell, people think orks are real wacky. Now, imagine yourself as a human on the receiving end of an orkish invasion.
Horrible green skinned beasts the size of an astartes, descending on your home in the thousands, in their smoke belching, ramshackle war machines, killing everything in their path.
As you try to escape the carnage through the back door, it suddenly shatters, a huge iron boot throwing you to the ground in a hail of shattered wood. One of the monsters stands before you, holding some kind of flame projector, and growls out in crude low gothic,
"Toim ta do da burny dance, you twiggy fing!"
Not so funny now, is it.
