hiking: a king of kings, a king who likes to hike or a king who says hi (compare and contrast: a knight who says ni)
Sorry to make a few of these, but I had several ideas ... Sore Loser - A person who has to keep buying new saws, because his old ones keep disappearing. Umpire - An umpire's anger. Debate - Taking the worm off the fish-hook. Empire - Help! The letter 'M' is on fire! Immigrate - I and me are wonderful. And you? Grenade - When you have to help someone smile.
