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 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.
