I learned yesterday from Function of の particle in the title 「進撃の巨人」 about one usage of the の particle, an example being 友達のコジ. I understand this as "(my) friend Koji". I also know that if you want to say "teacher Koji", you use コジ先生. I have two connected questions:
- Can you say 先生のコジ? If yes, does it mean the same as コジ先生?
- Can you say コジ友達?
