literally

*adds emphasis*

It's operates in a similar vein to the peppering of four letter words throughout a conversation, merely placing emphasis upon the encapsulating phrase, or the sentence as a whole.
It's like *look here, pay attention to me while I say this, though it is probably insubstantial and you might not want to regard it as wholly accurate if it is substantial.*

The earlier posts literally made such a big deal about the word being misused.

I literally had to correct that shit.

People are taking the definition of literally far too literally; I mean LITERALLY.

This is urban dictionary, it's literally made for incorrect colloquial usage cases. (this one happens to be both at once, which is likely why children first learn a mistaken use case)
