Ounce Town is like saying , I am going to take your girl friend or sister to pound town. But if you have a very small penis.
Hey baby, I am going to take you to ounce town, and give you the best 30 seconds of your life.
A "Colorado Ounce" is an ounce of marijuana composed of four individual quarter ounces of different strains of marijuana, named for the Colorado state recreational marijuana purchasing laws regarding out-of-state citizens, which often require a person to visit four different recreational marijuana shops, purchasing a quarter ounce from each, in order to leave the state with a full ounce of marijuana.
"I just picked up a Colorado Ounce from San Luis, let's smoke!"
"Let's drive up to Colorado and grab a couple COz's!"
