While having anal sex with a female, you fist the female, reaching through the wall separating the vagina from the anus and jack yourself off. Thus you are, "jacking, in the box"
The other day I gave this girl a "Jack in the Box".

A person whom gets in bed before their spouse,pulls the covers up tightly to their chest or mid-section. The individual then passes gas under the covers trapping the suprise. Once the bed time partner approaches the bedside, the person under the covers quickly removes the covers in the direction of their partner thereby throwing the previously trapped fart at their still standing partner while simotaneously yelling POW or BAM.
After chilli and burrito night i got to bed early to set up an epic jack in the box.

1. God's gift to himself, it is a restaurant chain on the west coast. Its fries are made out of 100% pure awesome and its burgers are an orgasm between two buns. They serve everything, and they do it well.

They had an E. Coli thing in 1993, which people STILL talk about when Jack In The Box is mentioned. Seriously people, it was almost two decades ago and JITB has not had any problems since. It is probably the SAFEST place to eat now. It's time to start opening them up out east again (they closed a lot of them after 1993). I would never eat McDonald's cow turd burgers again.

2. Children's toy... whatever.
Bill: Dude, I got you jack in the box.

Ted: No way! I love that place. What kind of burger did you get me?

Bill: I got you the toy *lol*

Ted: *punches Bill in the face*

When the tip of the penis pokes the entrance to the vagina (meant to be enticing). This process continues momentarily until the penis decides to make forcefull penetration.

One of the cruelest turn of events that could happen to any man. Where a female that one has been talking to for several months out of nowhere mentions her "boyfriend" that for some reason had never existed until that moment
Doug: Hey did you hook up with Courtney last night?
Cecil: Nawh! She brought up her Jack in the Box Boyfriend while we were watching a movie...I was shitty!
Doug: I had a bad feeling that was going to happen...damn!
