No I know
Another way of saying "No, really" or "Yeah, for real". It basically means you agree with someone's statement.
Person 1: Today is so cold I'm literally wearing two sweaters.
Person 2: No I know, it's so cold I'm actually thinking about wearing two pairs of socks.
Person 2: No I know, it's so cold I'm actually thinking about wearing two pairs of socks.
Get the No I know mug.
