Turning off all commuinication with the outside world (cell phones, phones, tv, computer, not answering door, having the dog(s)/cat(s)/kid(s) stay at the dogsitters/babysitters - to have mind-blowing, mind-altered sex.

Self-inflicted isolation for the purpose of re-booting the soul.

Lockdown, or Lockdown Mode, is when a public school building is literally locked down so that the Police, as well as the Great Drug-Sniffing Dogs, can search - without a warrant - lockers for drugs and other Contraband Items. And before you ask, yes it is constitutional. I am so sorry.
1. During the annual lockdown mode, we must turn off all the lights in the classroom and not move a muscle; if we are seen in the hallways we are automatically a suspect.

2. Many students question whether this Torture violates the fourth amendment - as there is search and seizure going on without a Warrant - but I'm afraid that you lose many constitutional rights when we go into our schools.

Lockdown is a fierce cybertronian that isn’t an autobot, nor a decepticon. He is a hunter with his own crew and was trying to capture Optimus prime and to bring him to his creators. Lockdown was sliced in half by Optimus Prime in AoE.
