"It seemed a fair trade for the happy mupple - the septuagenarian Englishman with his first-world passport but with his shuffling gait and warm if dribbling smile, and the teenage Filipina, grinning inanely as ever, with her whole life ahead of her but with two ex-husbands, an ever-expanding extended family and attendant work-shy village hangers-on to support. It wasn't so much they were made for eachother, rather they weren't really made for anybody else."
Whenever you want to say yes you say mupple instead. This word was inspired by a Police officer in training who really wants to be a cowboy. He is special. So go forth and use mupple wisely.
