Similar to a Poppy Johnson. If Poppy had a tumor removed from his butthole and it grew legs, wobbled around, and acted like a menopausal woman, that's a David Bradley. Will also plow over you like a steam roller in a mad dash to be the first to clock out and the end of a shift.
Person 1: "I refuse to work with you. Ever."
Person 2: "Don't be such a David Bradley"
