What is Barrel Rolls?
The clockwise or counterclockwise circular movement created by the contour of one's body when attempting to find a comfortable and successful sleep position. The individual may first try the "on the side" approach, but once that doesn't work, he/she may attempt to move to the "on the stomach" approach, followed by the "other side", and then finally "the back". Once the full circle fails, he/she then tries to repeat the entire process again, resulting in the form of a barrel roll.
Due to Paul's insomnia, he had a bad case of the barrel rolls for hours and then finally ended up just rubbing one out.
