Corvette Syndrome
A man who over-compensates for a small penis, genital deficiency, unattractive body, lack of personality and/or unattractive face, by flashing cash, or purchasing expensive items that he doesn't use, in an attempt to impress others.
Bobs trophy wife says he just purchased a new Harley Davidson, but he's never rode a motorcycle before. Apparently he's hung like a cashew, and suffers from "Corvette Syndrome".
