The act of buying and subsequently wearing a leather jacket in an effort to look tough, cool, virile, or otherwise appealing. A Fonzie Scheme is usually run by someone who in fact is NOT any of these things. The name derives from the name of Arthur Fonzarelli, star of the sitcom "Happy Days," who is the epitome of leather-jacket-wearing cool guys.
