A person who claims to be a fan of industrial music, but really only knows the band NIN and has a sychophantic reverence for Trent Reznor. Will ONLY shop at Hot Topic and thinks usually they are "More-Rivet-Than-Thou".
Me: So, what kind of music are you into?
NINny: Industrial. I am so fucking rivet.
Me: What bands do you like?
NINny: Nine Inch Nails. I LOVE Trent Reznor.
Me. Fucking NINny. It looks like Hot Topic threw up on you.
