Abbreviation of "picture fucker". Pixfuckers enjoy and value more pictured women than live ones. They specially like to collect quality erotica, softcore, hardcore and hentai pictures from free TGPs online. The essential piece of software for a pixfucker is ACDSee and Wallpaper Changer which they set to change the desktop background with a new random hottie every half an hour.
He's not gay nor shy, he's just a damn pixfucker webhead!
