What's the Rumpus?

I came home late on a Sunday, the house was a screaming zoo
 I couldn't tell if it was a party or a full on wrecking crew
 barrels of Booze in my bathroom, Bodies all over my floor
 they were charging me a cover at my own front door!
 When the whole thing's over, there's gonna be hell to pay,
 'Cause when its upside, downside, inside out, what more can you say?
 Hey Pah da-da-da-da yah hah hey What's the Rumpus?
 Hey Pah da-da-da-da yah hah hey What's the Rumpus?
 Hey Pah da-da-da-da yah hah hey What's the Rumpus?
 Cad e an sceil a buachail? What's the Rumpus?
 A pack of Peruvian peddlers, giving Guinness to their llamas
 One came out of my bedroom, he was wearing my best pajamas,
 Half a dozen dancers doing Hornpipes on the bar
 Something running in the kitchen, and it might have been my car
 When the whole thing's over, there's gonna be hell to pay,
 'Cause when its upside, downside inside out, what more can you say?
 Hey Pah da-da-da-da yah hah hey What's the Rumpus?

 Hey Pah da-da-da-da yah hah hey What's the Rumpus?
 Cad e an sceil a buachail? What's the Rumpus?
 Walshie's waltzing with a tree, pete and podge were on their backs
 Drunken Monkey's drinking draino and the guarda's in the jacks
 people hanging out my windows, and bowling down my hall
 Mad Music loud enough to shake the shingles off the wall.
 When the whole thing's over, there's gonna be hell to pay,
 'Cause when its upside, downside inside out, what more can you say?
