I didn't experience it personally, but while walking dogs with a friend and fellow F Plus listener, she told me a work story prefaced with the question "What kind of F Plus subject was this guy?"
My friend was working the late shift alone in a small specialty footwear shop. My friend is an attractive lady. A man entered the store towards the end of the evening and made a confusing request. When my friend indicated footwear on display, asking if these were what he was referring to, he became belligerent and accused her of "getting lost in" his eyes. When he finally got to the point where he was trying something on, he announced that it felt like he was "walking on spears". When asked to clarify this statement in a socially recognizable way he said it felt like his entire body was "made of spears".
MRA, PUA, or serial killer?
