Well, now that gallery is out and the qualifiers are over, I'm going to proceed further.
This work was planned as /mjg/ threads and Mahjong Soul 7th anniversary tribute.
Since it's the iceberg, it's meant to be fixed, updated and expanded more.
In fact, this general and /v/ threads previously have generated so much inner discourse it's hard to contain everything in the head and mention every single meme at once.
So, I ask (you) to help and participate in the contribution too.
A couple of threads earlier some anon said it lacks several ritualposts. It's not like literally every ritual post should make its way in. As you can see, for example, I didn't include hayasakatroon posting, fate/fgo, anything UmaMusu related. Well, you can count "Mortalbotting" line as fate reference, though.
I could forget something and I did miss a number of mjg happenings, that's another reason why I ask to help. Also, one anon thought I commited some serious mahjong crime. Please, elaborate, I'll see if I can do something.

What to add? From this year I still haven't add Zen Cynthia and Ichihime parasites. Should I an where?
What to change?
What to move?
What to remove?
