A Russian Rugburn is a sexual activity taking place between two people. The first person or the "Rug" goes multiple days or weeks without wiping after excreting bodily waste, causing the excess waste to stick and "crust". The second person in the activity lays down on their back shirtless. The "Rug" then stands above the second person without pants and begins to rub their unwiped behind against the chest of the receiver. Causing "rugburn"
