Head Over Heels

As I was talking to my leo the other day, he said "Sara, am head over heels in luv with you! no wait! heels over head! cuz literally head over heels is correct!"

anyhow, I did a little search, and this is what I found about the phrase "head over heels"

Meaning
Excited, and/or turning cartwheels to demonstrate one's excitement.

Origin
'Head over heels' is now most often used as part of 'head over heels in love'. When first coined it wasn't used that way though and referred exclusively to being temporarily the wrong way up. It is one of many similar phrases that we use to describe things that are not in their usual state - 'upside-down', 'topsy-turvy', 'topple up tail', 'arse over tea-kettle', 'bass-ackwards' etc.

Herbert Lawrence's 'Contemplative Man', 1771 is the first known citation of 'head over heels':

"He gave [him] such a violent involuntary kick in the Face, as drove him Head over Heels."

The first mention of love comes in 1834, by which time the phrase had crossed the Atlantic, and into David Crockett's 'Narrative of the life of David Crockett':

"I soon found myself head over heels in love with this girl."

Note: Non-American readers might not realize that Davy Crockett was a real person. Certainly in the UK he has the semi-mythic status of characters like Robin Hood and William Tell. Crockett is best known here by the old joke: "Did you know Davy Crockett had three ears? A left ear, a right ear and a wild frontier."

'Head over heels' is a good example of how language can communicate meaning even when it makes no literal sense. After all, our head is normally over our heels. The phrase originated in the 14th century as 'heels over head', meaning doing a cartwheel or somersault. This appeared later in Thomas Carlyle's 'History of Frederick the Great', 1864:
