"A minute": Not to be confused with 60 seconds. A minute is one of the most ambiguous measurements of Black time. What's a minute? It could be a few days, weeks, maybe years! So when you see your long-lost uncle at the cookout, expect him to say "man, I haven't seen you in a minute, nephew!"
McDonald's money: There’s more than meets the eye to this one. It is usually used by Black parents when their kids want fast food, but it can be applied to anything they ask for. It's a great way to teach the value of money pretty early, too. For example, "you can go only if you got McDonald's money."
"Around the corner": No GPS can give you better directions than Black people. Around the corner usually means something is close, but how close? That's up to interpretation. For example. "Oh yeah, I'm just around the corner from y’all."
"An arm and a leg": Commonly used by Black people when something is extremely expensive or requires much effort. For example, "Man, this watch cost me an arm and a leg."
Our unique units of measurement should be celebrated for their creativity and the joy they bring to Black culture. Every use of Black measurements is resistance to the white status quo.
