Multa cadunt inter calicem supremaque labra.
Horace.
To give one the slip. To steal off unperceived; to elude pursuit. A seaphrase. In fastening a cable to a buoy, the home end is slipped through the hawse-pipe. To give the slip is to cut away the cable, so as to avoid the noise of weighing anchor.
