Contrary to popular belief, rumpus doesn't mean your ass.
A rumpus is an activity that typically takes place after dark where a lot of people build a huge bonfire. They then paint their faces and/or arms and chest. You may also strip down to your skivvies but it's not necessary. After you're all dressed for the rumpus you dance around the fire and yell and sing. The object is to let your primal nature take over. This activity is mostly participated in by hippies. A rumpus took place in the book Where the Wild Things Are.
Example: "Hey Olivia, you coming to the rumpus tonight?"
"Hell yea! I love to rumpus!"
A dirty debatetactic; continuing to speak over your debate opponent while they are trying to speak, as to not allow them an opportunity to convey their point.
Example: Are you going to allow me to make m point, or are you just going to sit there and rumpus me?
