If you don't know what a mondegreen is, here's the Wikipedia entry. The Everlast song "What It's Like," contains the lines "Liked to get shit faced / And keep pace with thugs," meaning, to drink alcohol at the same rate as guys with greater body mass. Until I saw the lyrics, I misunderstood "keep pace with thugs" as "keep the basement dug". I thought this meant to raise enough money, by selling drugs on the corner, to keep a household going -- a "wife and kids" are mentioned a few lines later. To "keep the basement dug" seemed to be an expression that reflected the Sisyphean task of earning a meager income, only to have it all spent. The basement was a metaphor for a family's shelter. You keep digging, because if you stop, the basement will fill up again. It turns out there is no such expression.
