hi,
do you have the complete context where this phrase was used?
if it implies an amazement for something that is wonderful, it can be expressed as:
'cool'
'clever' / 'brilliant'
'excellent'
'bravo'
'perfect'
e.g. "Nakita mo ba kung paano n'ya minaneho 'yung sport car? Ang galing!"
"Did you see how he drove the sport car? Excellent!"
:)
