Answer 1

The name piranha may come from a hybrid language composed of Tupi-Guarani languages; it may be a compound word made of the components 'pirá', meaning 'fish', and 'sanha' or 'ranha', meaning 'tooth'. In Tupi, inalienably possessed nouns take the prefix 't-', 's-', or 'r-' depending on the possessor, or zero in combination; thus 'pirá'+'anha'. Alternatively, it may come from Tupi 'pirá' ('fish') and 'ánha' (devil). It is pronounced (in IPA) /pʰiɻanʲjə/ (or /pʰɻanʲjə/), /pʰiɻaʲɲə/, or /pʰiɻanʲə/).

Answer 2

Answer 3

Piranha is a fish, but in slang it  could also mean hooker.

Answer 4

It's a lot of common,  my mother's name for example is Verônica, it's a beautiful name, too.

Answer 5

It's that fish with lots of sharp tiny teeth and they are carnivore...well, it would mean a ***** in Brazil...of course it all depends on the context...
