A DJ trick. It is a method of cueing up records where the stylus (needle) is placed on the record at the beginning of the desired material and the record is held stationary while it slips on the rotating turntable. At the moment of truth, the record is let go, and almost instantly comes up to the speed of the turntable. This usually requires a special “slippery” record mat be placed over the normally rubber surface of the turntable. There are mats made especially for this.
