Basically, my friend died on a server I made for her, and this is what it said in console:
[20:18:12] [Server thread/INFO]: death.attack.no_water_for_gills
[20:18:24] [Server thread/INFO]: fucccck

I don't know how she died, but I'm sure you can figure it out.

death.attack.no_water_for_gills is the translation key for the death message for when a player that has the Merling origin dies if they haven't been in water for too long. It translates to "<username> didn't manage to keep wet"

To reiterate, this is still a bug and it didn't just say that in console, it says it in-game.

Yup, although it doesn't say the translated bit in chat, it said exactly what it said in console.
