I don’t understand the “Nobody” part, especially since in most memes it’s just blank. It makes sense when “Nobody” was saying something that most people disagree with, eg:
Nobody: I love slamming my fingers in a car door
Ford: New F-150 now comes with a dedicated finger-slamming door
That would make sense. It’s a joke about someone being out of touch with popular sentiment. But the ones where it’s:
Nobody:
Optimus prime taking a bath: Ahh, my electronics!
It seems like the nobody part doesn’t relate to the meme in any way, except for being a common format for presenting things.
I’m sure it’s intended to indicate that “nobody asked for…”, but personally I find that almost all memes that use it would be better off without it. It’s honestly kind of annoying.
