Right On

I was sitting in the car in the grocery store parking lot and I saw a young white man walking along with his shopping cart, only he was pulling it by its side rather than pushing it by its handle and he was talking on his cell phone at the same time. He was wearing possibly fancy sunglasses and a yin-and-yang t-shirt and he was smiling a big smile and screaming into his cell phone, "Right on! Excellent! Go for it!" He was just some happy dude going about his business.
