The nick name that you give your best friend especially when their name is
Maddy or
Madalena.
This is very useful in all situations. When you are mad at them, happy with them, sad with them, and so much more.
Happy: " I was rolling rolling rolling with the
madders madders madders..."
Sad: " OMG
Madders you can't just ignore me all day then facetime me at
12:30 A.M. "
Mad: " WTF
Maddy I don't even want to call you Madders anymore TBH"
