Spamming the same shit over and over without context IS the meme.
"Anime"
Alzheimers question
Coke with peanuts
This is all different forms of the exact same meme. It's only one meme, not separate memes.
Other memes are used often but often have a specific context and general meaning (a fucking leaf, etc), not just stuff that's spammed regardless of thread content or used as an OP in a thread without any ideas being expressed.
