>>112615420Vaggie is a fake meme cuckold. Jokes (memes) of Charlastor shippers here aside, Alastor is asexual in canon and Vivzie said that included not being romantically interested in Charlie. Charlie isn't interested in Alastor romantically or sexually in canon, either, It's a fan pairing.
Now Pearl:
>>112615441Was in love with someone who wound up with someone else in canon.
Does that make her a "cuck"? Actually does being cheated on even make someone a "cuck"? There are a lot of characters who have been cheated on.
But in popular language now, a "cuck" is actually someone who ENJOYS their partner sleeping with somebody else, as a fetish. That's the porn term. By this definition, Jerry's father Leonard from Rick & Morty is the only real "cuck" in cartoons that I can actually think of.
