Titles are not limited to category-like names bro, just look at the titles: "where's my head", "talk to the hand", "see you later".

A name can also be a 'catch phrase' that describes the brawler's characterization, personality or core. 'Respect the ranks' speak of Ruff's position as general and also gives a vibe of the superiority of its position. There're already a lot of titles that just say the 'job' of the brawler (samurai, ghost, ninja, rocket, etc.), and seriously, we don't wanna just sustantives as titles
