1. The senses. Used as an expression of intensity, especially in the phrases "beat/kick the living daylights out of someone" or "scare/frighten the living daylights out of someone." Jim had one too many drinks, picked a fight with a group of thugs, and had the living daylights beaten out of him! Don't sneak up on me like that—you scared the living daylights out of me!

2. obsolete The eyes. This was the original usage in the 18th century, but it eventually fell out of use and gave way to the more figurative definition above. Should that rapscallion show his mischievous face on my estate again, I shall blacken his living daylights without remorse or restraint!
