(Noun) Borrowed from the Argentine Spanish word "sobremesa". The action of taking a break after lunch or dinner. "Break" is code for catching up with the people you've just shared the meal with, usually for no reason.
-The lasagna was delicious, wasn't it?
-Yeah... by the way, what happened with Sally? I heard her husband cheated on her.
They went on talking about it for some minutes before doing the dishes (after meal).
