Scare quotes are quote marks which are not used to identify a direct quote, but rather to draw attention to a particular issue under discussion. There are a number of different ways to use scare quotes, but the most important thing to remember when using them is that they have a negative connotation. Before using scare quotes, you should consider the negative implications which go along with them.

One classical use of scare quotes comes up when someone wants to use a term while simultaneously distancing him or herself from it. For example, someone writing about self-improvement courses might use the term “self actualization” in scare quotes, indicating that the term comes from the organization offering the courses. The use of scare quotes also tends to cast doubt on the topic under discussion.

People also use scare quotes in a disparaging way, in which case they may become known as sneer quotes. Someone penning a furious letter to the editor about a meeting of a town's planning commission might use scare quotes like this: “Members of the 'planning commission' claim to be working for the town, but I think they are enacting policies which actually work against us.” In this sentence, the sneer quotes suggest that the planning commission is a disreputable body which is not doing its job.

You may also see scare quotes enclosing a slang term or unusual usage of a word, often in the distancing sense discussed in the second paragraph. A member of the older generation might, for example, put “rap music” in scare quotes to identify it as a slang term, while someone who wished do disparage the genre might say rap “music,” adding a sense of sarcasm.

The delicious irony and sarcasm of scare quotes is not limited to text. In spoken communications, people may crook their fingers above their heads and waggle them to suggest scare quotes while discussing something, for example, or they may change their tone of voice to identify scare quotes. In some cases, people may even make the scare quotes in spoken communications explicit, with a statement like: “The quote-unquote planning commission doesn't seem to be doing a very good job,” or “The quote humane society unquote seems to be killing a lot of animals.”

Scare quotes are often overused, so you should always evaluate a situation before applying them. Keep the sarcasm factor in mind when using scare quotes, as they often change the meaning of the enclosed word or phrase to its exact opposite. Would you buy fruit from a grocery store with “fresh fruit” in scare quotes, or insurance from a company advertising “low rates”?
