The opening of your digestive tract. It's Latin for "ring" or "circle". You know that muscle that contracts when you have to do number two? That's your anus. Also comically referred to as the distant planet "uranus".
Jeffrey Osborne - You Should be Mine (The Woo woo song)
A sympathetic bachelor woo woo wooing the love of his life, the apple of his eye, the bolognese sauce on his Italian sketti or the silence of his lambs. For the next six months he will wear his heart on his sleeves to charm that woman until she breaks his sweet little heart. That's when the lyrics change to, "And you boo hoo, hoo and you boo hoo hoo."
