How it's used
The term is primarily used as a noun, but it is almost exclusively paired with the verb 吹 to describe the action of whistling. When people want to describe the sound itself, they often just use the verb phrase rather than treating the noun as an independent entity. It is a common way to express lightheartedness or to get someone's attention in a casual setting.

Common mistake
