Vocal Yokle maneuver

When a high status & otherwise vocally articulate person deliberately speaks in very plain, simple, folksy, or uneducated language.

Often used by politicians, super rich, or other high status people when they want to see close to a lower status audience

Look at that fancy lawyer pulling the vocal yokle maneuver by speaking in super simple words to the jury as if he's not fancy, rich, & overeducated
