This (ab)use of literally doesn't mean its opposite, "figuratively". It's a sloppy shorthand for "without exaggeration".
"Without exaggeration, I got my ass kicked on the exam." = Right. "I literally got my ass kicked on the exam." = Wrong.
"Without exaggeration, I got my ass kicked on the exam." = Right. "I literally got my ass kicked on the exam." = Wrong.
He said: "I'm literally buggered".

Usually. I'm sure conditions exist where such a statement evaluates to true.
I see it similar to using \ in regular expressions. In the regular expression "\.", the \ acts much as the word literally, and modifies the special character so that I get the literal/actual meaning as opposed to the figurative/special meaning.
As for your example, I think it's meaningless. The phrase "fuck up" is a figure of speech, and has no literal meaning. It just has a meaning.
