A white proverb (2013) is an Internet meme on Tumblr where you quote something White Americans say to people of colour all the time and then call it a proverb. For example:
"I’m not racist! In fact, calling me racist is racist!"
— Ancient White Proverb
It is a joke: white people say these things so much and with such straight faces that it is almost like they were repeating ancient, wise sayings they learned somewhere.
