the closest thing to "jesus fucking christ" in my own work is probably the Arvan "Deyen Shessry"
Yirin i Shesrin (Shesrin Deyna by title, roughly meaning "the witch Shesrin") was a prominent priestess/sorceress/politician during the conquest of the Nerean Reach, and when early Arvan settlements in the area failed, the nobility blamed her for allegedly cursing the land (she probably didn't- Arvan farming methods just weren't well adapted to Nerean climates, and the local gods were less than friendly). a little linguistic drift later and cursing her name is a go-to for any moderate misfortunes one might encounter.
in the Nerean language, meanwhile, "e Shesrin" is both a family descriptor for her descendants and a term for students of her school of sorcery - but in slang is generally a celebratory way of calling someone promiscuous. like if "slut" had all pejorative connotations replaced with a cheer and a high five.
"tagrejye Shesry" - "three deeds of Shesrin" - is also a "fuck you" equivalent that would literally expand to "I will break your arms, piss on your father's grave, and fuck your wife", which she allegedly did to one of several rivals who tried to undermine her leadership (the exact target varies, but usually boils down to "the patriarch of one of the storyteller's family's rivals")
