Peri in peril

When I was a BMX kid, I was friends for a while with this wild dude - perpetually scruffy, rough with his bike, and didn't care about anything except big airs and powerslides. After he visited our place once to grab a cold drink, my mother told me privately he had the "dirtiest feet she'd ever seen". Anyway, to his credit, this guy just wasn't bothered by the small stuff. He had an unusual blue BMX that actually said "GMX" on the front. One time, another local kid tried to tease him, going, "That stands for GIRLS' Motorcross!" As his pal, I immediately insisted it didn't, offering some alternate explanation. The wild dude, looking completely unphased, went, "No, it does," and rode off. Some people are just born cool.
