At one point the Go FAQ said that Go got its name because “Ogle” would be a good name for a Go debugger [1]. This was removed from the FAQ as a "non-answer" in 2015 [2]. I suspect the real reason is that it was a slightly risque joke...

Of course the Go keyword go is a constant reminder of Go's strong support for concurrency. (Note too the goroutine/coroutine pun.) It would be interesting to know which came first, the keyword or the name.
