I think this song is about chilling with a band (or person) that you respect beyond words. You know it'll never happen again, but you live for the moment. The "crosses on our hands" are the black X's clubs put on people's hands, hence why they are not "for God." The never washing them off refers to not forgetting the wonderful night. With the "thank yous" it's also a bit of an idolatry song (maybe a musical idol), but you can also interpret it as a female narrator who's totally in love with a famous guy and the moments just won't last.
