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.
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.
A sexual maneuver, inspired by the classic N64 game, Star Fox 64.
While having intercourse in the missionary or upside down missionary position, the man firmly takes hold of the lady (preferably by the butt cheeks), and begins to log roll over and over.
Preferably, the man yells "Do a barrel roll!" or "Double tap R (or Z depending on the direction)!" or "Kiss my ass, Peppy!" as he pulls off this stunt.
