Prounounced similar to the greeting " alw right" in cockney speak. Normally refers to nonsense and hubristic behaviour. A sense of entitlement, maverrick behaviour, and hubris. The Rwhite believes themselves to be " right" at all times, a lessor known alternative to the caucasion Karen approach to life but with added confidence, to run roughshod over others. Typically a phrase from the Potteries and surrounding areas of Stoke on Trent. First seen as a typo in a local paper about council matters , but now in common use.
So she has gone Rwhite again! What is it this time? Rwhite behaviour really ruins things around here, and it keeps coming back!
