"Deepthroat" is a term that originally referred to a character in the 1972 pornographic film of the same name, which gained notoriety for its explicit content. The film became a cultural phenomenon and is often cited in discussions about the mainstreaming of pornography. The term has since evolved to be used informally to describe a specific sexual act involving deep oral penetration. Additionally, it was famously used as a pseudonym for the anonymous source in the Watergate scandal, further cementing its place in popular culture.
