Bare bum shuffle

When you have finished your business on the toilet and find some bastard has left you an empty toilet roll. You then shuffle across the bathroom bare arsed, with your pants around your ankles to get some loo paper from the cupboard.

Her "This morning you didn't replace the toilet paper"
Him "Hee, hee did you have to do the bare bum shuffle?"
Her (furious) "Yes!"
Him (having a hilarious mental picture) "Ha ha ha!!"
