Okay, this gave me a laugh! There is a difference between writing: " a privilege to be fucking with me" and a “fucking privilege to be with me!” I think they meant to word it the second way. Because, yes, #1 would definitely be a privilege!! 
Hahahaha right!!! I think I can clear this up a little bit @Kareness and this is something I just found out recently “fucking with someone” is a phrase used by the younger generation which means giving your attention to, spending time with or having someone in your life I believe. Like… if someone did me wrong I wouldn’t “fuck with them” anymore hopefully someone could explain this better than I can lol. 
I know it as ‘messing with someone’. For example, if someone is new to a construction site, they might be asked to go to the store to ‘buy a bucket of elbow grease’ or ‘striped paint’. That’s fucking with someone, at least it used to be, in the UK
This is so true.
