a girl in a group of other girls that is drastically uglier and broader than the rest often making them look better(may also be a cockblock). the term is derrived from the phrase "Designated ugly fat friend". The -y at the end is added so the word can be used freely in the presence of the duffy without making it obvious that you are making fun of her.
