"Groom kidnapping" is when a man is taken by force to marry a woman. This kind of thing is not allowed and is against the law in many places.
Imagine if you have a toy that you really like and don't want to share with anyone. But someone takes it away from you, even though you don't want them to. This is how the man feels when he is being kidnapped. He doesn't want to marry the woman, but someone is forcing him to. It is not okay to do this to someone.
People should be able to choose who they want to marry by themselves. No one should force them to do anything they don't want to do. It is important to respect other people's feelings and desires.
