Jumpers in the door 

U.S. Army Airborne slang for the phenomenon in which one has to shit so badly it could blow at any moment.

Having 'Jumpers in the door' is an emergency situation usually characterized by a frantic race to the toilet, and in which if a bathroom facility is not located immediately a huge mess in one's underwear could occur.

The actual phrase is coined after a chalk of U.S. Army paratroopers awaiting the green light during an Airborne operation, so they may exit the aircraft -- particularly the number 1 jumper who is waiting directly in front of the door for the light to change.

The civilian equivalent of this expression are, Turtlehead poking our, or TTF - Turd Touching Fabric

Dude #1, "Hey man, why are you walking like that? Where are you going in such a hurry??"

Dude #2, "Can't talk right now bro, got Jumpers in the door.."

From the Army Airborne community, need to take a dump VERY soon. Closely related to turtle necking

"I'd love to stay and chat, but I've got jumpers in the door."

When you have to take a dump and it feels like the tip is sticking out, much like when a skydiver stands in the door of a plane preparing to jump.

I had to hustle home after eating at Taco Bell because I had a jumper in the door.
