I catfished my brother-in-law.
Did you intend to hurt him by catfishing him?
No, I just thought it would be fun.
It's not right to catfish people, especially your brother-in-law, because he'll probably feel hurt and humiliated. You should apologize to him and stop catfishing people because if you don't then no one will trust you anymore.
It is not that big of a deal. It's all fun and games bro.
For you it is but for the people that you are catfishing it is not. It is mean and cruel to those people that you are catfishing.
