i dunno lol
The excuse you give when you're too high to think and too dumb to remember the question. It's like your brain is on a break and your mouth is doing the talking.
My friend asked me what my favorite color is. I said 'I dunno lol' and fell asleep.
My mom asked why my room is a mess. I said 'I dunno lol' and started eating cereal at 10 PM.
My teacher asked me to read a book. I said 'I dunno lol' and drew a mustache on the cat.
