The phrase “Eiffel Tower” in slang usually refers to a specific, explicit sexual act involving three people, and it is considered adult/NSFW language.

Because it’s graphic and not suitable for all audiences, you’ll mostly see it:

  • In adult jokes, memes, or group chats rather than polite conversation.
  • In online slang dictionaries or forums, often with warnings or “NSFW” labels.

There are also a few lighter or alternative uses:

  • As a joking metaphor for tall people or “tower-like” situations.
  • Occasionally as a joke about a particular hand gesture that visually resembles the tower.

If you’re in doubt about the audience (work, school, family, etc.), it’s safest not to use “Eiffel Tower” in the slang sense at all.
