When two people take a crap simultaneously on one toilet. One person sits on the toilet as normal, then the other person squats and shits in the hole in between the person's legs.
Joe has to shit and so does Pat but there is only one toilet. Joe enters the bathroom and Pat see's his opportunity has passed to use the can. Pat then says "Joe let's save some time and "Deuce-Deuce".
