A 'best girl' is a female character in an anime or video game series that is subjectively chosen to be the 'best.' The term 'best girl' is used by fans to express their opinion on their favorite character being superior to others based on individual traits they may possess, as well as their abilities.
'Who was the best girl in the series?'
'Well I'm not sure but I think it's definitely X.'
'No, Y was better. She was more mature and got along better with the main character.'

Old slang (dating at least as far back as 1927) meaning "girlfriend." Preferable in some ways for implying that she's not the only girlfriend, just your best.
