It wasn't supposed to stand for anything. Maybe it's just the area I live in or my age group, but alot of people on social media in my circle do things like that, where they throw internet acronyms together in a way that doesn't really make sense but you still get it's meaning.
Meaning in your brain you would subconsciously think "what the fuxed that for you" because you would think "fuck" and "fixed" at the same time.
Idk, it happens where I live. I live in Illinois, so I guess you can blame it on lingering effects of Rod.
