Used to describe a girl who was skinny when she was younger, but due to her genetics, became extremely fat after high school. Quoting the phrase, “she ballooned up”, and turning it into the name, “Balloonda”.
Damn, did you see Molly? She has to weigh at least 350 pounds. She was so thin in high school. She’s really a Balloonda now.
