Apparently, you're asking for a definition, but let's be real, you're clearly lost.
It turns out, "literally" is a word used to describe when something is, well, literally something.
However, in our postmodern, post-ironic society, "literally" has lost all meaning and is now just a word that means whatever we want it to mean.
So, to be clear, "literally" is like... uh... a chicken. No, wait, that's not right. It's like... a toaster. No, that's not it either.
