Used during the mid 18th century onwards in reference to the British Navy's great tradition of allowing no women on their ships of the fleet. The time when a Cabin Boy would have to wipe more than a smile from his face!
Person 1: "What is this navy all about then?"

Person 2: "Royal Navy, it's all rum and bum!"

"Rum, sodomy and the lash"

Get the Rum and bum mug.
Used to describe the runny, splattery, and gassy shits, usually experienced after a long night of consuming rum and cokes.
Wow, I’ve got a real bad case of rum bum today, I’ve gone shit three times in the last hour!

Get the Rum Bum mug.
The act of using pickle juice and rum for an enema. This is often done after a particularly violent anal cleaning.
I gave my ass hole a good cleaning in preparation for this Indian Rum Bum I'm about to get.
