a 'DK'
a guy who literally doesn’t know what’s going on. he’s the human version of ‘???’. he’s the reason you’re confused.
He said ‘what’ when I asked him what he was doing. That’s not even a question.
He walked into the room and didn’t know who I was. I’ve known him for 5 years.
He said he didn’t know what time it was. I said it was 3. He said ‘what’ again.
