Mandela Meme

It's when you're looking for a meme that you swore you got chuckles out of but can never find it anywhere. Did you just laugh at a meme made by the fourth dimensional beings? Or did you just found a glitch in the Matrix?

"Bro, look at this Leonardo DiCaprio meme"
"Wait who's Leonardo DiCaprio?"
"Oh shit we must've been Mandela Memed."
