Definition & Meaning of "bicycle"in English

What is the origin of the term "bicycle" and how is it used?

Bicycle refers to a person who is sexually attracted to both men and women. The term appeared in mid-20th-century English slang, likely drawing on the metaphor of "two wheels" to represent two sexes. It was mostly used within gay and bisexual circles as a casual, sometimes playful label, rather than a formal term. Today it is rare and somewhat dated, so it may confuse people outside historical or subcultural contexts.

What is the origin of the term "bicycle" and how is it used?

Bicycle is slang for a person—especially a woman—seen as sexually promiscuous or constantly switching partners. This meaning appeared in early–mid 20th-century English, probably building on the same "two wheels" metaphor to suggest movement or change. Unlike the bisexual sense, this usage is derogatory, often intended to shame or insult someone's sexual behavior, and is not considered neutral in modern conversation.
