BIG FAT GREEK, as in the type of guy who takes over your rommate's life because he is so into himself and being Greek, and thinks he is God's gift to all women. Everything he says is right by his standards and he is a cocky prick.

Val is such a BFG...damn guy thinks he's God's gift and every woman who looks at him should be bowing down to worship him. Go back to Greece buddy!!!
