Like another poster said, most memes have really short lifespans. Usually lasting only a month, maybe two at [i]most[/i]. Sometimes there are memes that are more popular that can last several months or even longer (e.g. We are Number One, his name is John Cena, Shrek, etc) and the very rare memes that seem to gain transcendence and become immortal, never going away or ever losing their popularity (e.g. Pepe, Trololo, Big Smoke's order). "Do you kno de wae?" does not appear to be one of these memes. I also suspect the Tide Pods meme will go the way of the dodo too soon enough.
