During male on male anal sex, the giving man uses any means available to cause a prolapse with the receiving man (pulling out at the immediate moment of a donkey punch is the most effective). The giving man then docks with the in-side-out anus. The star refers to the anus prior to prolapse.
That little boy is definitely gay. I overheard him talking with the game show host about star docking his brother while watching Family Game Night on "hub".
