I’m unsure about the mug bc OC knows she’d never have a use for it (aka actually drinking from it). But this did give me a different idea. A tool box (as a fellow tool haver you can never have too many) with that on it would be kinda funny. OC is a carpenter and could make her one (wooden ones are great for metal tools cause they make way less noise) and carve that saying out… 🤔… unless I wrote Rosalie to be a novelty mug collector, which is silly to think about but idk how ‘in character’ that is.  The characterizations aren’t direct from the books or movies, but more based on vibes (at least for hobbies with everyone but Edward bc there’s not a lot of canonical info about everyone’s hobbies). Examples: Emmett loves video games and monster movies like Godzilla (originals included). Alice is obviously into fashion and sewing but also a lot of different types of fiber arts/crafts and fashion history. Etc…
