The combination of the combat style dancing of Krumping, with the aerobatic stylings of Le Parkour, also known as free running. Invented by a group out of New Orleans called the 504 Krumpsters.
Rumpling is the art of shaking, then smashing a beer can into ones own skull until it erupts. The rumpler then pours the beer down his throat like the blood of his enemies. Most commonly occurs at fraternalgatherings and when that really sick EDM beat drops. May lead to concussions or you just looking plain bad ass.
