Son of a Crocodile
Terrans often call Shiss "Crocodiles" Even though they have nothing in common with a Terran Crocodile. During the First Union / Shiss War ( defending the Purple Throat Colonies) The Union Crews called all Shiss "Crocodile Faces" and the nickname prevails to this day. Especially Terrans and humans use it.
Son of a Crocodile is a variation of that theme.
