'Now see ere, ya gitz. Dere is dis cave, roight? No no, not a real cave, ya grot! Dis ere is a meta...metaf..a story cave, roight? An dere is orks sitting in dis cave! An deze orks haf lived in dis cave all dere lives since dey was gruntz. Now dere'z a roight big fire burning in diz cave, behind dem orks. And between dem orks an da fire dere is a gubbinz dat moves fings like dakka an stompa an choppa back an forth, so da orks see da shadow of dose fings on da cavewall.
Now, da orks ave never seen REAL dakka an choppa an such, so they'd assume dat da shadows they see are da real dakka an choppa! While every ork knows a shadow of a shoota ain't nearly as dakka as a real shoota! Stop laughin, ya grot! I'm tryin ter make a point ere!
So dem orks wouldn't know da real dakka if dey saw it! An if one of dose boyz went outta dat cave, he'd see all the fings he could stomp an wouldn't know he could stomp em! But if he stayed out da cave fer a while, he'd learn about da REAL dakka an choppa an speed, an den he could WAAAGH properly, like a real ork!
An if he went back into da cave, to tell da uvver orks about da real WAAAGH outside, they wouldn't believe him, see? Cause they'd fink da shadows were da real WAAAGH, so they'd stomp him fer bein unorky.
See, da point is..point is..dat you lot need ter WAAAGH as hard as yer can, cause yer might FINK yer WAAAGHing really hard, but it might not be da REAL WAAAGH! Now go stomp some humies!
