limey

You might hear someone called a "limey," but you should be careful with it. It began as a nickname for British sailors, and later for British people more generally, because British ships gave sailors lime juice to help prevent scurvy. The word has often been insulting, even if some people use it in a joking way. Whether it sounds playful or rude depends a lot on the situation and the speaker. The word can also be an adjective for something that tastes strongly of lime, like a limey drink or a limey sauce.

The term "limey" has a long history tied to life at sea. During the age of long voyages, scurvy was a serious danger for sailors. The British Navy became known for giving citrus juice to sailors to help prevent the disease, and this practice led to the nickname "lime-juicer" and then "limey." At first, the word referred mainly to British sailors, but it later widened to mean British people in general.

In many cases, the term was used as a joke, a taunt, or a mild insult. Because of that history, it can still sound offensive or patronizing, especially if it is used by a stranger or in a hostile way. Some speakers use it casually, especially in informal talk, but that does not make it safe in every setting. In formal or polite conversation, it is usually better to avoid it.

There is also a separate, literal use of "limey" as an adjective meaning tasting of lime or having a strong lime flavor. You might describe a drink, candy, or sauce that way. So the word can point either to an old and sometimes offensive nickname for a British person or to the taste of lime, and the meaning depends completely on the context.
