What he has on his arm is:
Nacer en El Perdriel fue y será lo mejor que me pasó en la vida
Transliteration:
Being born in/from Perdriel was and will be the best that happened in life.
Which translates as
The best that happened in my life was and will be being born in Stone Creek.
What should have been written is:
Nacer en El Pedriel siempre será lo mejor que me ha pasado en mi vida.
Transliteration:
Being born at/from Pedriel will always be the best that have happened in my life.
Which translates as
The best thing that have happened in my life has been born at Stone Creek.
Also, it should have replaced the other subject: 'Omega Hanggara' instead of 'Pedriel' It is not Perdriel. The tattoo artist made a huge misspell.
