This is the real origin of the term: dank is a
slang word from SF bay area that meant 'good weed, it's been around at least a decade.. eventually it just came to mean 'cool' in SF Bay Area Slang.. so seeing that tech culture emanates from the bay area
people just probly started saying "dank meme" as a
joke and others started using it ironically or unironically whether they knew or didnt know the origin. It's still a pretty dank word I use it all the time.
Original example as Bay Area Slang:
"Yo lets go score us some dank from that
guy you just met"
"
Ay this weed is dank as
fuck, where you get it?"
Contemporary example to refer to memes
"NORMIES CANT INTO DANK MEMES REEEEEEEEEEEEEEEEEEEEEEEEEEEEEE"
"I like that meme, it's pretty dank"
