Booby = a type of Gull. In the days of sail, on long voyages where fresh food was in short supply, sailors would set a trap to catch sea birds. A morsel of food would be placed on deck, in the centre of a rope noose. When a bird landed, the noose was rapidly drawn tight around it's legs, trapping the bird, or Booby, hence, booby trap.
