That reminds me of a time I went camping on a beach with a group of about 6 people. We found out one of the guys was afraid of sharks. We were walking after dark, about 20 meters from the water and a friend of a friend make a joke about "land shark", and the galeophobe jumped, turned, and asked "where?"

That is an attack in the same sense that when you step on a Lego at night, you are the victim of a Lego attack.
