Just like your favorite quarterback barking out audibles at the line of scrimmage, airlines have their own lingo they use to communicate. Pilots and flight attendants have words, phrases and jargon that might have you wondering why you weren’t aware blue juice was being served in the lavatory.

Here is a breakdown of what some of those sometimes cryptic messages mean…

Last Minute Paperwork – This means that there is a bit of hold up. Usually, a flight plan has been changed or maintenance is doing a write-up. Prepare for a 30 minute or so delay.

Crotch Watch – It’s not as creepy as it sounds, but it is the slang term used when flight attendants walk the aisle to check and ensure everyone is wearing their seat belt.

Gate Lice– Those odd people who rush to the gate to be first on board.

George – A name used to refer to autopilot.

Crosscheck – You usually hear this as you approach the gate. A lead flight attendant will announce, “Flight attendants, doors to arrival and crosscheck.” This just gives the signal that the staff need to disarm the emergency escape slides so they don’t billow out into the boarding tunnel upon opening the doors.

Air Pocket – A jolt of turbulence.

Cones or Coneheads – Students

Crumb Crunchers – Kids

Blue Juice – Despite the fact that this conjures up images of a delicious blueberry cocktail, you don’t want to drink it. When someone mentions “blue juice” on a plane they are referring to the water in the toilet. If you hear the pilot or flight attendant mention this…plan on crossing your legs.

Spinners – Passengers who board without an assigned seat.

Holding Pattern – During weather or air traffic delays, planes will make loops in the air until its their turn to land.

All Call – Think of it as a flight attendant conference call.

Deadstick – This is bad. It means the plane is flying without engine power.
