Damn, I have to play that solo soon and my clarinet's all full of my spit. I'll be getting fruzz like crazy if the repairman can't fix the pads on my clarinet in time!
A state of being which is feeling both exhausted and horny in equal measure and you don't know which one is going to win out. Obviously horny ultimately wins out but you don't know that when you're feeling so fluzzy.
