I'm surprised no one added Ugly Grandpa Range but the Temple of Ugly Grandma was mentioned lol.
To add constructively though, a lot of the names always threw me off -- Mhaura, Qufim, Adoulin, etc. were already used examples -- but the most confusing things I've seen are two mobs that don't really get much attention in the game as it stands nowadays:
Gwynn Ap Nudd
Rw Nw Prt M Hrw
Thankfully, the Wiki provides cultural information as to give some context to these, and many other mobs and items, as far as real life lore and myths (I mean, is no one gonna talk about all the other influences that have impacted FF as a whole?) but I'd really love to see the uninitiated and uncultured (for lack of a better word) really try their hands at those mobs lol.
