You're boss! That means I think you're great. So we would snap our fingers to Aztec Camera's Somewhere in my Heart on the radio, and agree that 'that song was boss', too. And Bruce Springsteen - how boss was the Boss?
Let me stop you there. Recent surveys have shown that Bruce Springsteen was, in fact, a Bent Over Sheep Shagger. Moreover, he's the bent-over sheep shagger, having pipped everyone else to the number one spot in a gruelling week-long animal shagathon.
He prefers the bent-over position, because he likes to feel the freshly shorn wool against his tummy, and this also allows another sheep to mount him, as he plays lucky Pierre in a raunchy ovine three-way.
Be careful when accepting this compliment, especially when it's preceded by "a", "the", or "my".
