Extremely happy, delighted, or excited about something.
This phrase comes from the nursery rhyme 'Hey Diddle Diddle,' which features a cow jumping over the moon. The impossibility and whimsy of this image made it perfect for describing joy so intense it seems to defy gravity and logic.
The phrase captures that feeling when happiness is so overwhelming it seems to lift us beyond earthly constraints. It's wonderful how a silly nursery rhyme gave us such a perfect metaphor for transcendent joy - sometimes the most childlike expressions are the most profound!
