When you do your work in your head but you have to show your work and you don't know how to do that because you have been doing work in your head so much you don't even need to visualize it
The first line of the song, "Man's Not Hot" by Big Shaq. It is a perfect opening line and captures the pure randomness of the song.
2 plus 2 is 4 minus 1 that's 3 quick maths. Every day man's on the block. Smoke trees. See your girl in the park. That girl is a uckers. When the ting went quack quack quack, you man were ducking.
