A Lane Estill
A Lane Estill is someone who copies people and then acts like they're the best thing since sliced bread.
She copied my dance and then said she was the best dancer in school. I told her to go eat a sandwich.
He copied my speech and then said he was the king of the school. I told him to go sit in the corner.
He copied my joke and then said he was the funniest person ever. I called him a lying idiot.
