goat freak
A goat freak is a "gear head" that really likes, and is very knowledgeable about, the Pontiac G T O that was originally made from 1964 till 1974 and then revived in 2004 with its early end after the 2006 model year. "The Goat" was a nickname for the G T O
Jeff sure is a goat freak with all his G T O s
