Other forms: scudding; scudded; scuds
To scud is to quickly dart or dash, the way clouds scud across the sky on a windy day or a sailboat scuds along the surface of a lake when it finally catches a breeze.
When something scuds, it's often because the wind seems to be blowing it along — so you might watch kites scud over the beach or birds scud from tree to tree. Experts aren't positive about the origins of this word, but one guess connects it to scut, "rabbit" or "rabbit's tail." The speed of something scudding influenced NATO's code name for the Soviet Union's Cold War-era missiles, Scuds.
