PRINCESS LEIA

From the character in Star Wars that can be subdued by three foot high teddy bears, but can strangle a 6'5 Storm Trooper with her bare hands when there's nobody around to rescue her. A person (usually female) who appears completely ineffective and useless until the pressure is on and then they turn into Rambo. Example: Give the work to Princess Leia, but don't expect a single line of code before the due date.
