What does ser imposible (una persona) mean?
Expression
to be impossible — about a person
Said of a person, imposible does not mean they do not exist: it means there is no reasoning with them. It is an affectionate surrender and it nearly always comes at the end of an argument that is going nowhere. Its relative is no hay quien te aguante, which is a good deal less affectionate.
Contigo no se puede. Eres imposible.
