n. An annoying little know-it-all who, in reality, knows little to nothing. They merely sit in class, take word-for-word notes (often in very neat or girly handwriting), and learn nothing, not allowing they're mind to wander and form its own thoughts, but to wallow in the mundane of that which has already been said. They, however, do wonderfully on class assignments, homework, and tests that require no individual thought because they delve so thoroughly into the cliché. They are so-named because they are very good a mimicing what a teacher just taught back to him via class discussion or, more commonly, essays.
Teacher: So, does anybody have any thoughts about the character Simon in The Lord of the Flies?
Parrot: I think he's a Christ-like figure because he goes off and prays and doesn't want people to fight anymore.
Teacher: Right, then, let me rephrase. Anybody with any original thoughts?
