backdoor 

A tactic that has been used many times in the American version of "Big Brother" where the Head of Household (because we Americans apparently cannot vote properly, so the housemates have to do it for us...HoH just nominates) nominates two pawns and then has one of his or her allies win the Power of Veto (a twist in the American Big Brother game that allows one of the nominations to be cancelled, or vetoed) so that the real threat in the game can be nominated and then subsequently evicted...in other words, evict them in such a way that they are sent "out the back door". Also referred to as "The Six-Finger Plan".

Nakomis pulled off one of the most innovative moves in "Big Brother" history when she nominated Marvin and Diane for eviction via "The Six-Finger Plan" to backdoor Jase and get him evicted from the house.

backdoor 

A piece of code built into software which allows it's creator entry. This type of system is usually unneccecary, but has two main reasons.

1. To automatically create an account with full priviledges that is hidden from the user(s) of the program, so any time they get locked out the creator can log in and solve the prblem for them (a maintenance account)
2. as above, but with ulterior motives. See spyware
3. As above, but because the software is not designed for used by it's creator.

Particularly common in movies about or involving computer hacking.

1. "The user had forgotten his password, so I had to use the backdoor and create him a clean account."

2. "The moron downloaded the program and now I'm watching his every move through the backdoor!"

3. "I was designing a new piece of control software for NASA, but I threw in an emergency backdoor as a precaution."
