Manda is a term used to describe a type of person.
These people are usually dim young white girls who believe that having a kid at the age of 14-17 is a career choice as the goverment will pay for the upkeep for the rest of their damn lives.

Manda is a very annoying bitch, she sucks a lot. When she enters your group chat you all groan because you don't want to talk to her. But behind all the teasing, you all really love Manda. She is very funny and creative, and you all love having her around. Stupid bitch.
