Meet Daniel S., aka. Mr. Sweet & Sour Pork,
According to Daniel S., this tattoo was intentional & he was "looking for something humorous, yet also an affront to those people who have supposedly 'deep' meanings in Chinese."
Although it is not incorrect, any serious foodie would know, Sweet & Sour Pork is actually written as 咕嚕肉.
A similar dish is called 酢豚 in Japan.
