Squawktard
A retarded person that utters a loud, harsh cry, as a duck, parrot, or other fowl might sound. Trust me dude, they are out there, and holy shit are they frightening!
Dude, I saw a squawktard today at a restaurant, and it was staring at me making this God awful sound. I thought they had a bird at first until I locked eyes with it, and it freaked out.
