I have a friend that is just like that, he looks and sounds like a chimpanzee with down, but in his head he's all swagged out.
One day we were at the sex shop with some other male friends he took up a penis shaped ruler and put his hand near the 4.5 inch mark as if trying to gauge his size. Then was like "yeah". I just thought to myself it was better if he thought he was Shane. The guy is very impressionable, and i don't want to ruin his buzz.
