pull chaulks

1) "Let's get out of here" or "Let's go". Used primarily by pilots, "Pull Chaulks" refers to pulling out the tire chaulks from either side of a plane's landing gear so that it can get underway. The words are often accompanied by a hand signal performed by holding two fists (with thumbs extended) together at mid-chest level and pulling each fist back towards it's corresponding shoulder. The verbal component and the hand signal are interchangable.

2) Can also be used to mean "Hurry up".
