This rule states that when masturbating with your right hand your thumb points in the direction the spooge will fly and your curled fingers will point in the direction your dick will bend if you jerk it with the right hand all the time.

There is actually a corresponding left hand rule that works the exact same way.
"It's good to be an ambitextrious masturbater.If you don't switch from your right hand once in awhile the right hand rule will tell you which way your dick will get bent."
