look up any word, like tbt:
 
1.
The act of having sex in a sleeping bag. Often because it is too cold to do it any where else. Difficult to perform well because of the limited space.

It bears some resemblance to the Kayak maneuver. There are invariably fluids deposited to the interior of the bag which are a minor annoyance, but which cannot be dealt with immediately. Often results in someone getting thrown out of the boat, much laughing and giggling by the participants, and jeers, applause and hoots by nearby campers.

Frequently performed by or with river guides, Climbing guides, etc.

John: "Yeah. I know. Everyone in the tent was laughing. I guess it was your turn."
