The 'croquet' is a folded cloth, but might just be there to signify an 's' sound -- in a hieroglyph dictionary [1] it says "lead" or "guide", `seshem`, maybe because the penis on its own can mean bull or donkey, so maybe referring to animals that must be lead, just a guess. Anyway its used at the front of a few names here referring to a leaders of one kind or another.
