Which is apparently perfectly grammatical to say now:

Gizmodo has discovered Google’s definition for literally includes this: “Used to acknowledge that something is not literally true but is used for emphasis or to express strong feeling.”

[...]

Merriam-Wesbter and Cambridgedictionaries have also added the informal, non-literal definition.

I understand that the English language is always changing, but a word like “literally” used to be taken… well .. literally.

This is going to throw a wrench into my plans today. No, not literally, though who really knows anymore.
