The friend described it as such:
"Go. is the coolest thing the t-shirt could say.
very powerful statement even if you don't think you've made it. even if it's in a lackadaisical manner or something. it's big. it makes as little sense as "Be Coming Up It" but you get the general sense that life is all about being bad ass as however you define bad ass."

But he's a bit strange.
