Cruising for sex, or cruising, is walking or driving about a locality in search of a sex partner, usually of the anonymous, casual, one-time variety. The term is also used when technology is used to find casual sex, such as using an Internet site or a telephone service.

Origin and historical usage

According to historian and author Tim Blanning, the term cruising originates from the Dutch equivalent kruisen.

In a specifically sexual context, the term "cruising" originally emerged as an argot "code word" in gay slang, by which those "in the know" would understand the speaker's unstated sexual intent, whereas most heterosexuals, on hearing the same word in the same context, would normally misread the speaker's intended meaning in the word's more common (and presumably less threatening) nonsexual sense. This served (and in some contexts, still serves) as a protective sociolinguistic mechanism for gay men to recognize each other, and avoid being recognized by those who may wish to do them harm in broader societies noted for their homophobia.
