A large obese boy/girl who resembles a person with down syndrome. They tends to think

of retarded nicknames for themselves in shape of odd intangible things. Also another easy way to

spot a Shamoo is to tell a funny joke, if he responds with laughter then he

might just be a fat ass, but if he looks into your eyes and rubs his johnson

vigorously you might have a Shamoo in the midst.This name can be given to any

one that meets the criteria, but is in best use if the names sound similar.
