Actually, it DOES mean he's a cuck. Textbook. The suggestion that it doesn't is a flagrant t disregard for the purpose of language and communication. I hate to get all specific with language and all, but, in truth, it is the very definition of a cuckold. We can't just throw words in the trash because the may be unflattering. Simple truth: If your wife has sex with other men, you know about it and don't take action AGAINST her, You are, IN FACT, a cuckold. Quit bitching about labels.
Is "cuck" a dirty word? Ok, it's not a word, but we get it. Like it or not, by definition, you are a cuckold ("cuck") if your wife is having sex with other men and you accept it.
My wife has cuckolded me. She takes greater offense at that word than I do. She Tries to deny the genuine reality. It does not change the fact that she has cuckolded me. (See? that wasn't hard...To not make it ALL ABOUT ME and MY EGO)I accept (and even participate with) her having sex wtih other men.
If your wife fucks other men and you are aware of it and you allow it YOU ARE A CUCK! DO NOT allow anyone to tell you differently. If you are to this point, who CARES?!?
If you like seeing other men fuck your wife, YOU ARE A CUCKOLD. It is a hard and fast definition, it is NOT open to interpretation. Do not let some asshole who avails himself of the status convince you that it's not true. If you are, in fact, a cuckold, LIKE I AM, , just put your false pride on a shelf and enjoy. It's 2017. I think it's silly to be "ashamed" of this "label".
You need to look up the term Stag, which have similar definition but without the caging a man's privates, or participating with the other male what so ever.
