Did someone say dank memes? M8 you're going to have to go all out. Latest trends might work, maybe dat boi would work. I don't think the memes from 2010-2013 are going to cut it, they're kind of stale now. You can probably find what's in from Vines, but you gotta be careful about the target audience because many people who would enjoy that might not be watching your channel.
I tried to use a 'dank' meme once, and it was basically Thomas the tank engine x rap, so you can try that as well. Anything that's hype.
