Exiting?

I could not find a meaning for "exiting" after seeing it here:

Ever since John Lydon a.k.a. Johnny Rotten, the lead singer of the infamous punk band Sex Pistols, took a Pink Floyd T-shirt and wrote "I HATE" on it back in the seventies, people have been able to speak their minds and express themselves through a graphic T-shirt.

“I’ve no idea where I got it from, it being green, which was an oddity… Not my colour. It might have been something I nicked off a stall. What I didn’t like about them was the pretentiousness. There was an aura of ‘Oh we’re so great there’s no room for anybody else.’" Johnny Rotten said when asked about the shirt.

I think this is as exiting today, as it was back in the seventies.

Long live the personalized graphic T-shirt!

What does it mean?

TIA.
