Speaking as a perpetual wallflower who has never been to a rave in my life, I found it understandable. Admittedly I’ve heard the term “molly” in reference to ecstasy, but you see as guy wide-eyed staring at someone who looks incredibly uncomfortable about it. Seems pretty obvious that’s the “molly bear” that uses “prolonged eye contact” to make “uh-ohs” so uncomfortable that they either leave or at least don’t come to another one.
