Full sail

When the fat guy in the hot tub lets his mid section rise to the surface and creates"Balls Island" He then pulls his scrotum vertically,thus creating a "Full Sail"

On a cold winter night in an outdoor hot tub at the Las Vagus Holiday Inn.Hendrix and his quarter ton comrades were concerned about the direction of the frigid desert air that was blowing across their tub.Hendrix,being the only one who finished high school,but was in the Navy for a short time before being dishonorably discharged had an idea.Being the most resourceful fella in the bunch he gently lets his mid section float to the surface of the hot tub,creating "Balls Island" from which he is able to yank his large scrotum skyward creating a "Full Sail" which gathers wind that he can now confirm is coming from an easterly direction.
