a degrating term used towards day laborers, who can only find work one day at a time. Because they cant hold a job or have a criminal record or are homeless.
we drove by the business and all the day lays came running out begging us to hire them for the day.

check out those day lays, they couldn't find a job today so they bought beer instead.
