I guess the small-souled are also small-chested.
This seems to be a double entendre - 性根 can mean "soul, character, spirit" but is also a euphemism for a penis. As I could not think of a suitable English punlation, I have left the literal meaning.What is this, a cutting board?It's crass to gloat over mere size. That's just like a kyuubi to do!
