Bucking the mustard is basically having diarrhea so bad it's squirting yellow from your rectum like someone's squeezing a bottle of mustard and it farts towards the end. Generally followed by the sound of someone scrubbing the shit splatters off the side of the bowl.

A buck who on his big night out says he is not going to drink much and will have an early night, whereas, in reality the reverse happens.
Igor is getting married so we took him out for his Bucks' party, we all thought it was going to be a quiet one until the drinking began. Never thought he would turn out to be a Reverse Irish Buck, he was soo drunk he passed out on the way to the wedding.
