#I believe Jack also complains that he isn’t spiky or smth

Has anyone made comments on the nickname that Floyd gave them? Even the teachers are called by nicknames, I think it's funny how everyone just casually accepts like it's a normal thing.

Yes, there have been instances of people commenting on Floyd's nicknames 😂 The main example I can think of is Grim in episode 4-24, but I'm sure there are also other times! (I believe Riddle in particular gets annoyed when Floyd refers to him as "Goldfishy".)

In 4, Grim is surprised by Floyd referring to him as "Baby Seal"; Floyd then explains the basis for the nickname (Grim is round and squishy like a baby seal!), and Jade elaborates that Floyd likes to give people sea creature nicknames. It's probably the case that everyone else has just accepted this quirk of Floyd's, and/or they've already had their nickname explained to them prior to Yuu showing up.
