taking two shits in immediate succession of each other. taking yet another shit when you've just finished a shit. happens especially after a night of heavy drinking, when you've just finished a serious beer shit, the ass juice isn't yet evaporated, you're getting off the crapper and you realize you have to go again. can be used as verb or noun.
