the act of completely fucking someone's mind.
getting inside someones head, and either convincing them of something, or causing them to question the reality of the situation.
after inceptioning someone it is imperative to say inception to the target, letting them know they just got mind fucked
Inception is also a game, with rules
*inception is a game best played lit as fuck, and is won when one person inceptions everyone in the room, regardless. you should always help out someone trying to inception another, by validating their story.
