Over The Moon
Meaning
This phrase is used when some one is very happy.
Origin
The first use of this phrase was in 1718 in Charles Molloy’s The Coquet, or, The English Chevalier:
“Tis he! I know him now: I shall jump over the Moon for Joy!”
Mother Goose’s Melody also had this phrase dated 1760:
High diddle diddle,
The Cat and the Fiddle,
The Cow jump’d over the Moon,
The little dog laugh’d to see such Craft,
And the Dish ran away with the Spoon.
