thattagirl or thatagirl or that a girl...however you wanna spell it is a derivative of "good girl" or "good job". So it basically means "good job" or "good girl" if someone directs this towards you.
It's short for "that girl". Both are correct, but "thatta girl" would be easier to read.
Do you mean "adda girl?" It means the same thing as "You go, girl!" "You rock, female!"
