A misspelled form of bah- fungoo, which is basically Italian for "stick it up your ass".
Person one: Hey, you're fat and ugly!
Person two: Bah fungu!
Person one: ???!?!

A mispelling of a the term "Bah Fungoo" apparently, wich is an term invented by Americans for a slang/dialect form of the Italian "Vaffanculo".
Bah Fungoo is in no way how it's said or spelled.
-What was that italian expression to tell you to fuck off?
-Bah Fungu? Bah Fungoo!
-Nah, neither, that's not italian at all.
