A way of expressing disbelief/anger while also insulting someone because they're a bitch. Can be used as a casual way of insulting your half-retarded friend while not actually insulting them. It's basically a real chill way of calling your friend a faggot.

When you say "are you fagging me?" your just saying "are you kidding me?" while also calling someone a faggot.

When you eat dirt for the first time and leave your family to build a shack in the woods
