Hello, and welcome back to Just Answer.The word 'Fuue' does not appear in any known language as a 'word' itself. If it's possible that you misspelled it and you meant 'Fue', it is Spanish, from the irregular verbs 'IR' (to go) and 'SER' (to be) and is a past tense meaning 'he, she or you went' (from IR) and 'he, she or you were' (from Ser).
If you possibly saw it in this comment from a video re: Justin Beiber, it was misspelled 'fuue' and meant 'you were'. http://www.youtube.com/watch?v=Z_ZGDbg2JoM
