1.
Indian Language (i forgot which one out of the 50+) word for black guy. Used instead of the N word so they won't get mad after they rob our convienence store and shoot us.
"Damn this kalu is entering my store. What is this? Damn kalu, trying to get a free slurpie, i'll show him."

"Excuse me, u kalu, you didn't pay your taxi fare."

"I called you a kalu, you know friend and faithful customer, please don't hurt me."
