Yoo-hoo is a call you use to get someone's attention when they are some way off, or when they haven't noticed you yet. You sing it out — the voice goes up and then down, like a little two-note tune — and you often wave at the same time.

Yoo-hoo yoo-hoo is是 a call you use to get someone's attention一種呼喊，用來引起某人的注意 when they are some way off用在有人離得有點遠, or when they haven't noticed you yet或還沒注意到你的時候。You sing it out你會把它唱出來 — the voice goes up and then down聲音先上揚再下降, like a little two-note tune像個小小的兩音旋律 — and you often wave at the same time而且通常同時會揮手。

You use it across a car park, up a staircase, into a garden, or through an open door when you arrive at a friend's house: 'Yoo-hoo! Anyone home?' The feeling of it matters more than the meaning.

It is friendly, cheerful, and soft — you would use it with a friend, a neighbour, a child, never to a stranger in a serious situation and never to a boss. It also carries an old-fashioned and slightly feminine flavour; in films and TV it is often a woman calling to someone she knows well, and people today often say it as a small joke, putting on a sing-song voice.
