When you are reading a manga/manhwa or watching an anime and something cute or hot happens, then you need to get away from ur phone/pc for a bit to process what just happened, so u run laps (probably around ur house)
A saying that is applied when somethimg is falling on or chasing someone, and instead of turning and running to get out of the path of the object, this person runs straight instead.
The man ran was about to be crushed by the falling building because he obviously went to the prometheus school of running away from things.
