2.
A person who decides to shell off current technology, and live in the past. They do things like replacing DV cameras with super8 cameras,tossing out overly "advanced" video games, replacing them with atari 2600's, as well as tossing out CDs, and replacing them with good 'ole records. They aslo change they're clothing wearing 80's trends, and doing things like growing mullets.
I'm a retroist!
