OK but please tell me why when you're asking for a name of something you call it sauce?

It's an Internet slang for ''source''.   reply

It's a misspelling of "Source" and now internet likes to use it from now on.   2 reply

Idk either. I guess this is another weeb kind of language?   reply

im honestly not sure either but i think it means the name of sth like if someone saw a fan art of sth and they dont know the name of the show they'd ask "sauce?"   reply

I've been wondering about this as well   reply
