When did ‘literally’ become, literally, the most annoying word in the English language? Fairly recently I would guess, because ‘like’ as in ‘I was like… seriously?’ or ‘that’s like, so unfair’ was easily winning the title for many years. ‘Like’ has become a filler, taking the place of um and er, and generally making the speaker sound a bit of a moron but literally (used to) have some authority, emphasising the slightly unexpected veracity of whatever.
