A whinger is a person who whinges — someone who complains constantly about small things until everyone around them is tired of it. It is a label you put on a person, and it is an insult, though usually a mild and slightly joking one. 'Don't be such a whinger.' 'He's the office whinger.' Everything true about whinge is true here too, especially the region. Whinger belongs to British, Australian, and New Zealand English; the American equivalent is whiner or complainer. In Australia it is a very ordinary bit of everyday speech. The meaning is fairly narrow: it is about *habit*. A whinger is not someone who complained once about something real — it is someone who does it all the time, as a personality. That is what makes it stick as a name for a person. A note on spelling and confusion. There is a completely separate old word, whinger, meaning a short sword or a large knife. You will meet it only in old books about Scotland and England, and it is pronounced with a hard g. The living, everyday word — the one you need — is the complainer, from whinge, with a soft 'j' sound. Same letters, different words.

（英式、澳式英語）愛抱怨的人、成天發牢騷的人，接近台灣說的「愛靠北的人」「碎念王」。語氣是輕度的嘲諷。美式英語會說 whiner 或 complainer。另有一個完全不同的古字 whinger 指短劍，只在古書出現，不用管它。
