From this post:
Ms: Same for niggardly or tar baby. You still have dindu, though.
Waiter: “These Blacks always leave niggardly tips!”
Boss: “Racist! You’re fired!”
Waiter: No! You don’t understand! Not niggerly tips, niggardly tips!
Boss: I’m calling the SPLC!
Waiter: “WTF did you flunk English 10?”
Interesting tidbit: The word “niggardly” apparently comes from the Old English word, nig, “stingy”, 1300, Middle English. Possibly borrowed from Scandinavian nygg, “stingy”, which may be from Old Norse nigla, “to make a fuss about small matters. -ard, Middle English “pejorative”. So nig + ard, “stingy” + “lowlife”. Niggard, “stingy lowlife,” niggardly, “acting like a stingy lowlife, miserly, tight, cheap, stingy, etc.”
I didn’t know nig meant stingy. I always thought it meant something else.
