When your having drinks with your mates and one person grabs the beer box, slaps it on the ground (indoors) infront of everyone, pulls down his pants (or hers) and slops out a mass mud monkey for the rest to see. The person will then run to the toilet to clean up, usually leaving a bread crum trail.
Daniel called us all over and gave us 'The Dee Zee' last night... It was stanky!!
