When trying to get friend A to be in trouble with friend B by telling friend B that friend A did something that they should be offended by.
Friend A to Friend B: Yo, why didn't you give me a pen when I asked for it the first time?
Me to Friend B: Are you going to let her talk to you that way after doing her a favor?
Friend A to Me: Why you have to be so mixxy all the time ?She don't care. Right, Friend B?
