Title text: Suckville is considered by the Census Bureau to be part of the Detroit metropolitan statistical area, despite not being located anywhere near Detroit.
Megan and Cueball are playing a card game, perhaps Dominion, or Magic: The Gathering, or another card game involving piles of characters facing each other. and Megan whips a common insult, a play on the word "suck" and adds a typical city name to the end of it. Other variations are: "losertown", "lameville", etc.
The phrase is originally based on the ubiquitous signage you see along roads that say "Welcome to Town X - Population Y".
Then, since Cueball one-ups Megan by indicating there is a city by that name, she can only resign herself to the fact that her smack talk did not work.
The title text says that Suckville is classified as part of the Detroit area despite not being in the Detroit area. Indeed, looking in the factfinder Suckville is "corrected" to Saukville, Wisconsin. Which is not anywhere near Detroit, Michigan.
- [Megan is kneeling on the floor, playing a card game.]
- Megan: Hah! -- Welcome to Suckville - population: you.
- [Cueball is sitting on the floor opposite her, also playing the game.]
- Cueball: Why are you using 2000 census data? -- That's an old figure.
- [Megan turns around from the game to look at her laptop, which is sitting on the floor behind her.]
- Megan: I couldn't find Suckville in the 2010 census.
- Cueball: Huh? It's right there in SF-1 table P1.
- Megan: Oh. So it is.
- [Megan turns back to Cueball, who is looking at his cards.]
- Megan: Well, then. Welcome to Suckville - population: 83.
- Cueball: Much better.
