...You share pictures leading up to the fight of topless Men saying "WOW! Watch out John, Bryan is in INSANE shape". It's borderline homoerotic. You get guys on here commenting on Conors/Lukes bulge, on how so-and-so has the potential to be a star cause they're 'handsome', yada-yada.
You also have fans who apply a hero worship/infatuation to Male Fighters, they wish they were like them and really look up to them. One could easily break down fandom of MMA, especially the adoration for big muscular heavyweights as something 'odd' and 'creepy'.
