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.
"What is that creature lurking in the mist" "Oh that's just Shamoo Schaller"
