When one sneaks into the bathroom while another person is showering and takes a shit; the person showering is less likely to hear the perpetrator's entrance, allowing for the perfect opportunity to attempt a sneaky dan.
"dude should I go in there and shit while Kyle is in the shower?"
"you're gonna give him a sneaky dan?!.... thaaat's greasy."
"you're gonna give him a sneaky dan?!.... thaaat's greasy."
