Unlike “cuckold”, “chupim” isn’t really sexual. It’s mostly that sort of person who wants everything, but never gives back.
For example. You and your brother got each their own toys. If you play with his toys, he throws a tantrum: “THEY’RE MINE!”. If you don’t let him play with your toys, he also throws a tantrum: “WAAAAH YOU’RE SELFISH!”. That’s a chupim.
In the USA the name cuckoo is also used to refer to people who like to do… a thing.
