In those scenarios cuck does not apply. If the guy is actively making content with their girl, it's not cuckish at all. The term can be used somewhat broadly, but can apply to when the guy is not a major participant in the situation. He doesn't do a lot of content with her and when he does it's pretty awkward and a lot of people complain about it. It's an assumption that he gets off to the idea that other dudes are getting off to his girl, which may be wrong to assume, but also maybe not. He may one day be okay with her making content with other guys, or mabye not, we'll just haveto wait and see.
