Military term for taking a dump. Originally came from the command Air Assault soldiers use to order the helicopter crew chief to drop the cargo load carried underneath the chopper.
Dude! I'll be back in 10-15, I've got to go cut sling load something fierce.

Military hand and arm signal given to a helicopter pilot when their rope-suspended cargo is liable to cause the aircraft to go out of control. It is issued by holding the left arm out horizontally hand in a fist, knuckles up and then waving the right arm at the elbow so that the knuckles pass under the left elbow in a cutting motion. It is a term that signifies dropping a topic, problem or person in a hasty and irrevocably conclusive manner.
I wasn't getting anywhere with Suzy last night at the club, so I cut sling load and went on to Jess.
