Is an idiom which means a person feels very, very, very happy.
For example: I am lucky enough to have a teckie knight in shining armour who continues to make me feel over the moon. He first fixed my laptop after I gave it some lunch of rice soup, he then fixed it again when the keyboard decided to have a schizophrenic episode, and then in the middle of August the sun decided to fry part of the boot up system. On all three occasions, I was jumping up and down, clapping my hands, whooping with sheer bliss – I was over the moon. Subsequently, I think I’m now banned from the shop.
