Maybe you might be surprised by the original definition, also teached by Vera F Birkenbiehl, what a "meme" really is" and how close that comes to the very base what your "definition" of a "meme" is.
"i cogito, ergo sum"
"I think, therefore i'm."
~ RenΓ© Descartes
"i sentio, ergo sum"
"i feel, therefore i am and i think"
"hmm, that made me think"
"you feel&think, therefore you are vulnerable, or not (you apathetic asshole - lol)."
Meme: Virus of/in your thoughts/mindset/spirit.
You just referred to the optical representation to it.
It also could be propaganda resp. FUD.
And even then it would be a meme.
lol
