Have A Gay Old Time: Anime and Manga

Traditional:

  • One Piece referred to a certain stream as the "Knock-up Stream" (in those exact words, even in the Japanese version). One Piece: Grand Adventure, which had its dub made by 4Kids, referred to it as the "water spout", but Pirates Carnival called it the Knock-Up Stream.
  • Fairy Tail having the main characters be part of a guild the same name is fine, but then you get some weirdness in the times when someone calls a member of said guild "a fairy".

  • The English dub of Chrono Crusade uses accurate 1920s slang which causes this to occur.

Intentional:

  • Done intentionally in Full Metal Panic!, where at one point Tessa (a submarine captain who is posing as a junior high student at the moment) says she's got experience in "the water business", which is Japanese slang for prostitution. Kaname responds with a muttered "That's kind of a poor choice of words..."
