It's weird how many shirts there are in Asia with English gibberish. They just have no idea...also why do they consider English on t-shirts to be cool?
Actually, for all you know they /can/ understand it and are wearing shirts like that for fun or cause the print looks cool. I live in Singapore (English speaking Asian country *gasp* shocker) and I see loads of people wear shirts with something ridiculous printed on them.
What's bape
