When one takes Adderall when one is still half asleep, whilst setting one's alarm to go off ten minutes into the future. When the alarm goes off, one will find oneself jumping up, suddenly wide awake. Popping up out of one's bed like that fey, much-celebrated children's toy of yesteryear.
Jack: Give me some of your 10 mg generics, I am going to need to pull a Jack-in-the-box this morning.

The unfortunate but hilarious consequence of having sex with a woman less than six weeks after a C-Section, resulting in the penis stabbing out of the closed wound. Commonly known to happen Kentucky.
Woman: WHY THE FUCK IS YOUR PENIS STICKING OUT OF MY BELLY BUTTON?!
Man: WOW this looks like a Jack in the box... A KENTUCKY Jack in the Box!
Man: WOW this looks like a Jack in the box... A KENTUCKY Jack in the Box!

Back in the good old days, some Jack in the Box workers would throw in a free gift like a balloon after you ordered food. Later you could buy items of their now forgotten characters: Onion Ring Thing, Hambugermeister, Small Fry, Secret Sauce Agent and Jack.

A Miami-Jack-in-the-Box is when a guy takes a small cardboard box (like a jack-in-the-box) with a lid, cuts out the bottom, places his penis through it, has a girl open it with her mouth, and then she gives him a blow job.
There is no example for the Miami Jack-in-the-Box.
