I have come upon an expression and I don't quite know which language it comes from (if it does). I've done extensive but superficial research online for each word on it's own, but I couldn't find any links between the words to make sense out of the whole expression. I don't speak japanese, and actually the only languages I speak are portuguese and english, although I have knowledge of some other languages.

I don't have any context or additional info available to help, unfortunately.

The expression is "nagamis teme". No other writing of that sentence is known to me, if it ever exists.

I have, on my research, found that in Yoron there is a compound word which pronunciation is "nagamis" and means "rainy season", and I know from japanese cultural influences on western culture that "teme" is a negative way to refer to someone in a conversation, but it don't quite know if those two references make up a valid sentence or expression.

Looking for more about Yoron words, I found JLect and I'm hoping that someone will be able to give me some help on this.

I appreciate any help and thank in advance.
