Too too fu fu is the slang for toddlers that could mean fuck you, train or what ever context they use it. Takes extreem caution in the facial expressions and tone while it is being said. There is no rhyme or reason to this word but is starting to be an epidemic amongst toddlers.
Eat your supper or you’re going to bed, “too too fu fu” fine! bed time crying “too too fu fu” pointing at a stuft animal.
