"mock" + "offended". Someone is moffended when they are only pretending to be upset or angry at someone else. They
aren't ACTUALLY offended, but
maybe just a little, and want to make the person feel guilty while keeping things
light-hearted.

Warren: I can't believe you would do that to me!
Caleb: Oh
please, I know you aren't
mad - you're just moffended!
