Top definition
A drinking apparatus to consume large amounts of rum in a short amount of time. Consists of several feet of tubing connected to a valve and another section of tubing a few inches long. The tube is inserted into the rum, preferably a 2 liter of rum & coke, which is placed above the drinker, either at the top of stairs or a loft. The valve is opened and gravity forces rum down the tube and into your throat. Guaranteed to mess you up.
Holy hell, we downed that half gallon of rum in like... 20 minutes. I don't even feel a thing though.
(10 minutes later)
Dude, i'm not feeling too good... that Rum Bong really messed me up. I can barely walk.
