A "Techno Punk" is someone who:
-Has or has had odd-coloured hair
-Is also a Mindless Self Indulgence fan
Kind of like a club kid without the Michael Alig, the psycho clothes, and the hardcore drug use.
Also known as an "Electro Kid".
Much like a Technemo.
Techno Punk #1: I like bands like Mindless Self Indulgence, Alexisonfire, SMB, My Chemical Romance, Retard-O-Bot, Underoath, Vyncent Flaw, and He Is Legend! And I just died my previously pink hair green!
Techno Punk #2: Oh my! That means you're a techno punk!
