小五ロリ
A [[meme]] associated with [[Komeiji Satori]]. It's a visual pun: The word 悟り (which means "enlightenment" and is pronounced as [i]satori[/i], although it's not written the same as Satori's name) can be broken down into constituent radicals as 小五ロリ, which roughly means "5th grade elementary school [[loli]]".
