The expression is "fare-thee-well", not "fare-the-well". Personally, I have never head "back and belly". I have heard, "beat (someone) until (he's) black and blue." As someone else said, there are also a number of vulgar expressions which mean to beat (someone) severely. One of them is "to beat the crap out of (someone)". Other, even more vulgar words can be substituted for "crap".

I agree with the above comments. Though I want to add that I have never heard "kick the Jesus" but people in America often say "kick the bejesus out of someone."

I have never heard "back and belly" or "knock the Jesus", but the others are common. Knock/beat/kick the stuffing out of sb Knock/beat/kick sb into Kingdom come Knock/beat/kick the tar out of sb Beat sb six ways from Sunday There are lots of profanity laced versions, too!

In the US, the first, second and fifth are fairly common. The second one is often heard with "hell" replacing "daylights".

Thank you, Matt. Which two expressions would you call the most common?
