To become milkmired means that you have aged like milk, in contrast to someone who ages like wine. It is a portmanteau of milk and expired. Sometimes the term "sexually expired" is used. Milkmirers often face the unfortunate side-effect of not being able to date people their own age: only older. A denarian (teen) milkmirer looks like a vicenarian. A vicenarian milkmirer looks like a tricenarian. As such, young milkmirers are indirectly forced to interact with milfs, cougars, manthers, sugar mommas and cradle robbers whether that is their niche or not.
