Question: Whenever Kevin talks to Mack, Kevin calls him "Mack Daddy." Mack always responds with "Don't call me that." What is the reason Mack doesn't like to be called "Mack Daddy"?
Question: At the end of the episode why does Daria look down and say "Damn" to herself?
Answer: Earlier, Quinn prods Daria to imagine having the object of her infatuation, Trent, as an actual boyfriend, and to picture her dream exactly the way it will be. Then, Daria's imagination turns her dream of being with Trent into an extremely unpleasant future, and Daria says, "I think I just got over something," which means she got over her infatuation with Trent. At the end of the episode, Trent tells Daria that it's too bad she's not older, so he could take *her* out, then he leaves. Daria then envisions a romanticized future with her perfect Trent, and in this dream Trent tells her, "Daria, you're the best thing that ever happened to me." And just like that, Daria's infatuation with Trent is back, and Daria exclaims, "Damn," in frustration.
Answer: "Mack Daddy" was a 90s phrase meaning "Ladies man," and Mack simply doesn't like the stupid nickname.
