l0jb4n

''w00t'' is quite certainly an attitudinal, but it should translate to
something which is not quite correct Lojban. I'd say that Lojban for
''w00t'' could be __o6__. It's pronounced ''oxa'' which sounds like
__o'a__. --[rab.spir]

''j00'' could be ''d0'', but frankly I don't think there is a serious
overlap between people who say these things and people who speak
l0jb4n. Some of us even use ''zo'o'' in instead of '';-)''. -
