Social Engineering is when you manage to convince someone to do what you want them to, when they normally wouldn't want to. This also includes when you convince someone you are someone you are not.
These tropes are well used by Social Experts (its super trope The Face), High School Hustlers, Guile Heroes, and Manipulative Bastards. It's also often the modus operandi of a Con Man. Also frequently used by real-life hackers (from where the term originated). Those posts on social media saying your Drag Queen name is your childhood pet plus the street you grew up on? Those are password recovery questions. Hackers use the information provided in questions like that to gain access to people's online accounts all the time, but Hollywood would have you believe it was pure techno-wizardry.
