Cover art for Milk lyrics by Kings of Leon

Actually, I think this song's full of sexual innuendo.

'Salty leave' sounds like a pun on tears and semen. Milk sounds like the latter as well. 'Being school tardy'? What about not liking to rush the morning after? 'She'll loan you her toothbrush' if you haven't got one of your own... that being typical if it's a one-night stand. And taking generic stereotyping to the max, bartending hardly sounds like something a sweet, innocent girl would do, eh?

Ahh, what filthy minds these blokes have.

Spot on!
