While looking up the spelling for literally (I’m a terrible speller), I came across this interesting note in the old Merriam-Webster
1 : in a literal sense or manner : ACTUALLY <took the remark literally> <was literally insane>
2 : in effect : VIRTUALLY <will literally turn the world upside down to combat cruelty or injustice — Norman Cousins>
usage Since some people take sense 2 to be the opposite of sense 1, it has been frequently criticized as a misuse. Instead, the use is pure hyperbole intended to gain emphasis, but it often appears in contexts where no additional emphasis is necessary.
I recall David Cross poking fun at people who do that last part.
Oh, and “hyperbole”: that’ll get you 25 cents fo’ sho’.
