Her: "Sorry, we have to cancel girls night. I forgot that Boyfriend has custody of his kids tonight and so I have to make them dinner, help them with their homework, and prepare their school lunch for tomorrow."
Friend: "Girl, he's using you as a bang nanny! DTMFA."
a person who is very sassy and therefore deserves the degrading position of a nanny. this is the negative use. the positive use is like calling your friend idiot even though you are kidding.gaskin
A nany is super awesome and super hilarious and knows how to crack people up. She has a great personality. She rocks and is super sweet and talented and guys better treat her right cos she’s a literal queen she’s super silly all the time and rocks :)
