Mrs. Tall had a very clever pet parrot, and when her friend, Mrs. Small, came to tea, she could not resist showing him off.
"If you pull this little string on his right leg," explained Mrs. Tall, "He"ll sing the national anthem. And if you pull the string on his left leg, he'll sing Roll Out The Barrel."
"That's amazing," replied Mrs. Small. "What happens if you pull both strings at once?"
"I fall off my perch, you silly old twit," repiled the parrot.
What is the closest meaning of the underlined word "twit" ?
