I found this passage quite hilarious:

"It is then customary for the female to then give a quick blow into the anus for good luck, the lips blowing into the anus sounds very similar to a trombones sweet melody."

rotflmfaooooooo, on what planet??!  In any case, I can't stop humming Sousa tunes in my head since I read the Urban Dictionary listings for it... lol

~ Seventy-six trombones, dah, dah-dah dah-dah... ~
