A situation where one character says a word or phrase in a non "Double Entendre" (or sometimes not even Innocent Innuendo) manner, but another takes it the wrong way and starts laughing. Bonus points if the first person tells the second to "grow up" or something similar. The amused character saying "That's What She Said!" has the same effect. Compare That Came Out Wrong (Heh heh... "came") and Accidental Innuendo (Heh heh... in-your-endo) . Contrast Innocent Innuendo (Heh heh... "innuendo" again) and oh would you be quiet!!
