breeder

Most often used in the derogatory to describe people that elect the suburban middle class lifestyle because they are so inept the only possible way they can contribute anything to society is to produce offspring. Typical cycle goes as follows: schooling -> job -> marriage -> children -> death. Their children also tend to grow up to become breeders and the cycle continues. True "breeders" can be compared to animals such as rabbits or cattle that do nothing but multiply by breeding. The term probably got its start in the GLBT community but has since gained outside popularity.
