To deceive or cheat.

ETYMOLOGY: gullible - 1793, of uncertain origin. Gull was a cant term for "dupe, sucker" (1594), perhaps from the bird, or from 16c. gull "to swallow" (from O.Fr. goule, from L. gula "throat"); in either case with a sense of "someone who will swallow anything thrown at him." Another possibility is 14c. dial. gull "newly hatched bird," perhaps from O.N. golr "yellow," from the hue of its down

Opinions vary to applicability of either word to me.
