Definition & Meaning of "dildo"in English

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

"Dildo" originally referred to a sexual object, with the word appearing in English by the late 16th century, possibly from Italian or Spanish origins, though the exact etymology is unclear. By the 20th century, it began to be used figuratively as an insult for a stupid, foolish, or worthless person, drawing on the metaphor of uselessness or absurdity. It is most common in informal, humorous, or vulgar speech, often among peers or in comedic contexts. The term is derogatory and crude, and while it can be used jokingly, it is not neutral and carries strong disrespect when directed at someone.
