A dance performed with your drunken friends at a bar. Most appropriate to perform when you are absolutely hammered, and "All Night Long" by Lionel Richie is playing. The dance consists of jumping up and down in a circle, spilling your beer over the entire bar population who are staring at you in pure disbelief.
Steve-O: "Man that was a great karamu last night at McGee's"
Gibb: "Yea man the best bar I've been to in my entire life!"
