The balls of a extrmely sexually challenged male. The name goff balls was taken from the first known case. Included in the Goff balls disease is the symptom of an extremley small penis, below one inch even if erected. Goff balls must be handled with great care, or are prone to damage.
GOSH DANG! They are some tiny balls you have, they are goff balls!
