豪情壯志is a Chinese saying that means “heroic sentiment and robust determination”. KFC’s Slogan is 豪情壯翅 , or “heroic sentiment and robust wings!”
KFC is about the best advertiser in Taiwan. Heck, they’re getting free advertising from me, they’re so funny! I don’t really feel like translating the whole commercial though, so if you don’t find it funny just pass it along to a Chinese friend. That way somebody will enjoy it besides just me.
