I have a coworker who uses 'literally' incorrectly

You realize that this is parody, right? And skilful parody. It squeezes in five precisely analogous constructions to intensify metaphors within in the peeve.

really makes my blood boil [but not really]
truly a plague [but not truly]
really laid-back [but not really]
actually drives me insane [but not actually]
In fact, it’s quite soul-crushing. [but that’s not a fact]

Another giveaway is the tongue-in-cheek

which is a parody of similar constructions such as
I’m not a racist, but…
I generally support LGBT rights, but…
