he ate his friend named seagull so he called the thing he ate seagull soup?

Yes.

They were stranded on this on this island, and they were hungry so this one guy killed the others and called it seagull soup, he liked. He swam back to land and got to a restaurant ordered seagull soup, realized he ate his friends, ran out and got hit by a car.

allright im going to solve it
he was on an island or something in the ocean, which would explain him swimming in his clothes..but he was starnded there with his friend, named seagull
a long time passes with out food, so a fight ensues, the man kills seagull, and eats him naming this food seagull soup, then after awhile when his food runs out, he swims back to a beach somewhere .. he finds the restaurant..and he is so starving he seas seagull soup and orders it.. but then he realizes that he ate his friend and he called it seagull soup, so he got so sick inside, that he couldnt bear it.and he ran out. and got hit by a car or something

You googling bitch.
The official answer:

A man was stranded on an island with two other men. One of the other men, decideds to kill the third man for food. The first man is unaware that the second man killed the third, he simply thinks that the third man commited suicide. So he enjoys this "meal" that the second man had cooked up, which he called seagull soup. When he swims back to shore, he stops in this restaurant and is pleasently suprised to see his new favorite meal on the menu. He orders it, takes a bite, realizes it taste nothing like the soup from the island, and it becomoes clear that he ate his friend. He runs into the road and dies. :)
