A nickname for cheap beer, like Natural Light, or Keystone. Cheap beer one resorts to buying when they have a mortgage.
Not anymore, now I drink mortgage beer.

Natty Light.

The sober-up beer, typically the last beer of the evening, is perfect for when you're either overserved or too full and need just one more before you go home. A watery, domestic light beer usually fits the bill, perfectly balancing hops, barley, and hydration.
"Hey Mike, do you need another drink? No, I've got an early morning…make it a sober-up beer."
