An attempted keg stand with no help from anyone whatsoever. Usually resulting in utter failure (knocked over keg, face plant, etc). Believed to be started by a drunken FSU fan celebrating their victory over Boston College on November 3rd, 2007.
i was at my a party at my friends apartment the other night, when i heard someone holler "Portuguese Keg stand" and then proceed to dive head-first onto the keg. Hilarity ensued.
