When you first get into Reggaeton you want to cover everything you own in a Puerto Rican or Dominican flag: Car hoods, head, head rests, bed spreads, and skin. The problem is that there are companies that actually make these products.
But if you take it this far and you are not actually Puerto Rican you can get into some pretty awkward and potentially dangerous situations. But, you can't just NOT represent Puerto Rico or else you'll just be like every other jerk. Instead, you just need to find a way to show your love of PR without going over the top.
We recommend getting a small flag that you can hang in the front window of your house or from the rear view mirror of your car.
You can always buy one on ebay.
