I've used some real-life vulgarity as Jana, largely inspired by Sergeant Swygrael in the relevant Moogle Mail quest; unfortunately I cannot remember the exact vulgarities she used... Only that I was surprised she used it. But I took it as evidence that our everyday swear words probably exist in Eorzea. Even it's it the sort of thing that only a pirate would use, Jana spent a lot of time studying in La Noscea, nervously rubbing elbows with them.
While I would like to get into the habit of using "colorful" Eorzean swears, Jana curses (aloud) so rarely that a single F-bomb often feels more impactful.
