The art of dropping a deuce over a previous deuce that has clogged a toilet. The act of double stacking most frequently occurs during emergencies and is generally considered bad form.
Bill could not hold the deuce brewing inside him and his only option was to use the clogged toilet in the hotel room he was sharing. Bill ended up double stacking in the toilet.
