Median Girls

Everyone getting together is a good norm,
Let's try again in this team.
Each hint is given in some form,
Venerating our advertised theme.

En passant twice isn't "doubly rude",
New responses don't always come out;
Low effort house memes are no good,
Every grandmaster meme is dank? I doubt.

The solution to atomic is still miles away,
Try solving 7x7 Chess instead.
Even letterspacing can be a clue, I say,
Roll up everything in your head!

Special hint: what do I like a lot when creating names?
