A wolf-whistle is a particular loud whistle — two notes, one sliding up and one sliding down — that a man makes at a woman in the street to say he finds her body attractive. It is both a noun ('he gave her a wolf-whistle') and a verb ('he wolf-whistled at her').

A wolf-whistle is a particular loud whistlewolf-whistle是一種特別的大聲口哨——two notes, one sliding up and one sliding down兩個音，一個滑上去、一個滑下來——that a man makes at a woman in the street是男人在街上對女人吹的，to say he finds her body attractive用來表示他覺得她的身材很吸引人。It is both a noun它可以當名詞（'he gave her a wolf-whistle'『he gave her a wolf-whistle』），and a verb也可以當動詞（'he wolf-whistled at her'『he wolf-whistled at her』）。

The important thing is not the sound but what English speakers now feel about it. Fifty years ago it was often shown in films as cheeky or even flattering. Today it is widely treated as a form of street harassment: unwanted, aggressive, and something that makes women feel unsafe rather than admired. In some countries it can even be reported to the police.

The important thing is not the sound重點不是那個聲音，but what English speakers now feel about it而是說英語的人現在對它的感覺。Fifty years ago it was often shown in films as cheeky or even flattering五十年前電影裡常把它演成頑皮甚至討人喜歡的舉動。Today it is widely treated as a form of street harassment現在它普遍被當成一種街頭騷擾：unwanted, aggressive不受歡迎、帶有攻擊性，and something that makes women feel unsafe rather than admired而且會讓女性感到不安全，而不是被讚美。In some countries it can even be reported to the police在有些國家甚至可以報警。

So when the word appears in modern English, it almost always carries disapproval — writers use it as an example of bad behaviour. Because of that history, you will also often meet it in discussions of how attitudes have changed ('back then, wolf-whistling was normal').
