Top Definition
A Baseball Player who played his best years in Oakland on steroids. In 2004 when he was on the Yankees, he testified that he took many steroids, admitting that he was a steroid taking asshole, unlike mark mcgwire and barry bonds who "didn't know" he was taking steroids. Giambi is slowly regaining baseball skills, but he will never be as good as he was while on the juice.
Person: Jason Giambi is a steroid taking asshole
Other Person: At least he admitted he was taking steroids, unlike other assholes
