Raindrops

I recently overheard someone use the phrase "here was a guy who could walk between the raindrops" to describe someone. What exactly does it mean, and is it common in some region?

I don't know if it's regional. I think it means the guy is really, really skinny.

Or it could mean he's very graceful.

I always thought it meant he had some sort of divine protection. Kind of like saying he could walk on water.

There are several entries for "skinny" in This Dog'll Really Hunt: An Entertaining Texas Dictionary by Wallace O. Chariton (Wordware Publishing, Piano, Texas, 1989, 1990). One is: "He's so skinny he would have to run around in a shower to get wet." Kind of similar to the phrase in question. I guess reading the phrase in context would help determine whether the guy was skinny, divine or graceful.

My husband offers another opinion: he thinks it means the guy is always lucky.
