Nderakóre
It's a very popular and common Guarani-Paraguayan interjection word with a very strong meaning, translated to english: "your vagina/p***y". It is used as an expression of perplexity, confusion, surprise or great disgust. It is considered very explicit, it has led to watered-down versions used to avoid censorship. Then, it is said indistinctly: “ndéra” or “kóre”, wich both are valid. In turn, these two versions are used in combination with various other words.
Nderakóre, ndajerái... (For the p***y... drunkenness does not go away); Nderakóre, chera'a! (in guaraní "ra'a" means friend).
