A man who lets his wife or girlfriend have sex with other men. Often the man lets her do whatever she wants and treat him like shit.
(Short version of cuckold)
John watched his wife get fucked by another man. What a cuck!
Get the cuck mug.
A man who is desperate for acceptance, approval, and affection from women. This desperation has led to the compromise of his beliefs and values, the desecration of his dignity and self-worth, and his inability to stand up for himself and what he deserves as a human being, eg. loyalty, fidelity, and honesty in a romantic relationship.
I know John's always wanted a girlfriend but since him and Mary started dating he's become a cuck. She spends all of his money and flirts openly with other men. I can tell it bothers him but he's so afraid of losing her that he doesn't say anything.
