There are tons but I know some…
[I know that I’m missing some more but these are what I currently know on the top of my head.]
I understand that
and the character’s meme: Just search “姦 meme” and you’ll know.
Also, 轟
if you search-image “轟”, you’ll get the My Hero Academia character since his full name is “轟 焦凍” (とどろき しょうと) /Todoroki Shō to/.
For the last image (龍), I will zoom the image for better focus.
I hope that this helps?
