No, no, please don't explain

From later in that article on Rubin:

"Although Rubin's parents — his father was a shoe wholesaler, and "my mother's job was me" — wanted him to be a lawyer, he had other ideas. In 1983, while he was attending N.Y.U., he borrowed $5,000 from his parents and recorded "It's Yours" by T La Rock and Jazzy Jay, a 12-inch single that became a local dance hit. Rubin then invented a label, calling his company Def Jam ("Def" meaning great, and "Jam" meaning music) . . . "
