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.

The act of chugging LIQUOR and liquor only from a handle on command when the proper phrase "Do a barrel roll!" is used.

While in the act of sexual intercourse, the man must be laying on his back and his partner on top of him. Just as the man is about to ejaculate, he grabs his partner close into his chest and rolls off the bed or couch onto the floor with her.
