In all the world, Pisu (Pisu 
, פיסו 
) is quite a rare unisex first name. The forename Pisu is habitual in Italy, where it is a rare epicene name, Romania, where it is a rare boy's name, and India, where it is a very rare largely masculine, but infrequently feminine name. Measured by absolute frequency, it is the most numerous in India, Italy, and Nigeria. More frequently, Pisu is the last name as well as the forename.
