drop in, drop out 

"Drop in, drop out" usually refers to online video game playing where any player wishing to join the game in progress can "drop in" and assume instant control of a NPC (computer controlled player), without any significant disruption to the gameplay. The player can also leave and return control of the character to the computer - "drop out" again without causing disruption to the game.

Gears of War offers drop in, drop out gameplay where any player can assume control of Dominic Santiago, Marcus Fenix's best friend, without freezing or restarting the level. World of Warcraft also offers this feature.

turn on, tune in, drop out 

A term coined by Timothy Leary to describe the psychedelic experience. Leary explains it in his book Flashbacks as such

“Turn on’ meant go within to activate your neural and genetic equipment. Become sensitive to the many and various levels of consciousness and the specific triggers that engage them. Drugs were one way to accomplish this end. ‘Tune in’ meant interact harmoniously with the world around you – externalize, materialize, express your new internal perspectives. Drop out suggested an elective, selective, graceful process of detachment from involuntary or unconscious commitments. ‘Drop Out’ meant self-reliance, a discovery of one’s singularity, a commitment to mobility, choice, and change. Unhappily my explanations of this sequence of personal development were often misinterpreted to mean ‘Get stoned and abandon all constructive activity.”

"Like every great religion of the past we seek to find the divinity within and to express this revelation in a life of glorification and the worship of God. These ancient goals we define in the metaphor of the present — turn on, tune in, drop out." - Timothy Leary
