Roped is a term used to describe a maneuver that occurs when you as a higher energy fighter pull into a vertical climb, luring your lower energy opponent to follow you. When he stalls out, you nose over and end up on his 6. He has been "roped", or "rope-a-doped".
Cherry picked is used to describe when a fighter drops down onto a low and slow...or damaged...aircraft and scores the easy kill. Basically, any time your opponent can do nothing about the situation...like being on the ground, deadstick, whatever, and you kill him, you went cherry picking.
