I often come across this phrase "fresh off the back of something" and although I could never find it in a dictionary, I figured out it means "right after something" but what does it really mean "off the back"? Why is the word "back" used in this phrase?
OED has a draft entry from 2010:
I suppose it may come from horse-riding, referring either to riding on, or jumping off from, the back of an animal.
