when you have anal sex with girlfriend of over 1 year. the catch is shes too afraid of pregnancy through ass so you need a condom, but you dont have one, thus using basketball shorts as your condom.
hard boner going through basketball shorts into ass hence...THE G JOB
When you get dressed up like Obi Wan Kenobi during sex including a neon blue, glow in the dark condom as your light saber. when you shoot your load you say, "MAY THE FORCE BE WITH YOU"
Yoda gave the obi wan to young anikan skywalker, turning him over to Senator Palpatine and the DARK SIDE!
