A MoMo is a loud and obnoxious girl who doesn't settle until she gets her way. She can be rude and doesn't like to think before she acts. MoMo is usually a nickname given to a girl named Maureen but sometimes girls like Monica wish their name could be sprinkled with the greatness of the title MoMo.
"Yo who wants to rap battle me?".
"No one would verse you".
"Because you are MoMo and can't be defeated".
