Definition & Meaning of "schlong"in English

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

Schlong is a slang term that appeared in English in the early 20th century, borrowed from the Yiddish word shlang, meaning "tube" or "snake." It came to refer specifically to the male genitalia because of its long, cylindrical shape. Historically, it was informal and crude, often used in joking, sexual, or vulgar contexts. Today it remains colloquial and sexual, commonly appearing in casual or humorous speech rather than polite or medical conversation.
