Here is a quote from article:
The largest animals ever to have lived on Earth, blue whales are colossal in every respect — including, it must be said, the scatological. When a blue whale goes, it goes big.
I’m not native speaker, but it is pretty clear to what does it mean “when it goes, it goes big”. But it is clear for me only because of the context in which I’ve encountered this phrase.
My question is: As for native speaker, is this very phrase clear without any context provided?
