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 pretty sure it’s implying that nobody asked at all; like, literally no one is asking about it. Knowyourmeme explains that it’s, “…a phrasal template used to mock people who strive to attract attention and tend to provide unsolicited opinions, as well as for observational humor.”
