Stop "creating memes". This is what's wrong with the imageboards, all sorts of people circlejerking about what "memes" they're "creating".
I'll sidestep the fact that "meme" is an unfortunate and stupid term for the time being. Really, the more important point is that the in-jokes of any community are not "created" - they develop and evolve naturally. Trying to be an authoritative source on what is funny and what gets shared and repeated is like putting yourself on a pedestal as some sort of "meme missionary".
Just try to be a regular, normal poster like everyone else, and eventually you'll find that someone else has repeated something you wrote.
