The term "JDM Tyte" has found most use on Automotive Message boards (mostly ToyotaCelicas.com). It's definition is composed of a double standard:
1. It's usually defined as a Japanese car that has been modified with tacky, ugly, and stupid parts that the owner feels is extremely cool. See Ricer
2. However it can also be defined as a Japanese car that has been upgraded rather well with expensive, rare, and effective car parts.
1. d00d! Those clear tailights are JDM tyte, yo!
2. Holy crap, that ST185 is JDM tytely tuned!
