Grudge racing - racing for those too poor and/or too stupid to race competitively.
Don't believe it? Check out what happens to 95% of grudge racers when they show up at a real event. I watch the motorcycle guys show up to "show how it's done" every race. It's HILARIOUS.
I have street raced plenty, but the secret squirrel shit like Little Village does is silly, especially when you're posting videos online. ProTip: If you're trying to be secretive, you're doing it wrong.
