This is when a bit before you wake up in the morning, you have a sexy wet dream. And when you wake up, you have an extreme urge to masturbate, and you usually do so. For the rest of the day you tend to have a hyper libido.
"Sorry I'm late for school today. I woke up with morning horny and missed the bus."
This is when you are getting a handjob from a woman, and right when you're about to blow your load, you shove an apple in her vagina and put on a pair of glasses and yell "I'm slowly dying of insulinoma!" and then you blow your load on her and take a picture of her vagina with your iOS device. Then you call all of your friends on facetime and describe to them how "revolutionary" it is to get a Steve Job.
"Man, I'm still tuckered out from that Steve Job Jessica gave me last night! She sure can pack it in!"
