My contributions - the technical term is "filiform corrosion" and is informally known as "worm tracks". You can find these terms in the technical literature. Snakes under the paint seems just as good as worm tracks.

The times I've seen it, the cause was traced to chlorine ions, caused by failure to properly clean a plated part.

Rust never sleeps. My bike has some under the paint. I'm too lazy and too stupid to do anything about it.
