So, you get morning wood, eh? But do you ever get....night rock? This is when you try to go to sleep at night, but that girl from earlier stays in your mind and gives you an erection that prevents you from sleeping.
Guy 1: Awww man, I'm so tired today. Barely slept last night...
Guy 2: Why? Bangin' a girl?
Guy 1: No, I was thinking of that, but night rock kept me up all night!
