VampireHunterRene said: its called pimping not cheating
No, pimping isn't when you yourself have sex with multiple women, its when you hire/force women to have sex with multiple men for profit, and then take a most of that profit they earn for yourself.
Cheating is the correct term for unimale multifemale relationships in humans, at least in situations where two of the individuals are pair bonded as proven by religious and/or legal documentation.
Without that documentated pair-bonding, its something else entirely, of course.
