In Clint Eastwood's award-winning film Million Dollar Baby, Clint's character is an aging trainer/manager of boxers who, against his better judgement, takes on a young woman (Hillary Swank, in an Oscar-winning performance) as client/protege.

The setting and the characters are American as can be, but Eastwood's character is studying Irish Gaelic langauge as a sort of hobby, and Swank's has an Irish name (Maggie Fitz-something) although little or no knowledge of or interest in Irish history and culture. When the young female boxer begins to experience real success and goes off to Germany to fight a world-title contender, her manager surprises her with a green-and-gold robe inscribed on the back with the words "Mo Cuisle." She has no idea what it means, and Eastwood's character won't tell her, but the crowd includes enough exiled Irish boxing fans to raise an enthusiastic chant of "Macushla! Macushla!" The meaning is not revealed right away, but Maggie's new nickname catches on as she rises to international prominence, and eventually we learn that it means something along the lines of "sweetheart" or "my darling."

I won't give away any more, for those of you who haven't seen it and may want to check it out. I'll just say this: if you expect an old-fashioned-Hollywood "happy ending," prepare to be disappointed...
