You could take this as another asinine example of sexism in advertising, or you could consider it an extremely obscure and witty reference to the bloody imagery in the epic 9th Century Skaldic poem, Haraldskvæði, by Thórbiörn Hornklofi:
I'll ask of the berserks, you tasters of blood,
Those intrepid heroes, how are they treated,
Those who wade out into battle?
Wolf-skinned they are called. In battle
They bear bloody shields.
Red with blood are their spears when they come to fight.
They form a closed group.
The prince in his wisdom puts trust in such men
Who hack through enemy shields
|"Oh, I get it! Brilliant juxtaposition of the blood of death with the blood of life!"|
Oh, who am I kidding? It's just another asinine example of sexism in advertising.
