What does "royally" mean here? I don't think you'd say "royally f**ked up" in the conversation!
Hahah :) No, you usually do not say "royally f**ked up" in every day conversation. However, this is an expression in English. You would only say this if something really bad has happened and you are so shocked that you don't know what to say. "Royally" in this sentence means to be extremely or to the highest degree. When someone says "royally f**ked up" they are saying that this thing is the most f**ked up thing ever to happen.
