Man, I had a "friend" like that. He didn't boast so much on sexual conquests, but he would brag about how he has practiced various martial (surprise, surprise, the guy was overweight), and make detailed descriptions of games that he has played (that didn't actually exist), including some Duke Nukem Vrs James Bond, a Siphon Filter game for the Saturn (with random nudity), and an R-rated Super Smash Bros. movie. He was also obssessed with wrestling and whenever he rented a game I would have to watch him create a wrestler for 2 fucking hours. Somewhat similar to your friend he also talked about Dragon Ball Z and power levels
