ink is a nickname kinda guy. he calls everyone nicknames- some silly and some sweet and some that make you go ???? part of it is due to his memory issues, remembering names he comes up with himself is easier than just flat out remembering names
YES I AGREE i dont have many thoughts on ink but i definitely have picked up your headcannon of this from speaking to you- i especially like and agree that he'd come up with them from memory issues
i also think this means he'd have multiple nicknames for everybody and they'd change often, it depends how easily you can associate the thing he's using as a nickname with that person
