A euphemism for an adult male, usually over 30 years of age, who holds a dead end job paying no more that 30,000 dollars per year. A McClurg may also live with his mother, or at least in the basement of a relative. Another defining characteristic of a McClurg is a heavy five-o-clock shadow that never seems to go away no matter how much he shaves.
