Coined by high school kids in Anoka, Minnesota years ago, but when a neighboring suburb got their own high school, Andover High School, they tried to claim it as their own (despite most of those students originally from Anoka High). Then Anoka High School slaps them back with "The Real A-Town" in an effort to reclaim it.
Basically just one of those individual suburb things where kids get so stressed and hyped up over little things that don't really matter. Doesn't make anyone better than the other, yet they actually fight over it.
Andover High kid - "You said you're from Anoka, right?"
Anoka High kid - "Yeah. A-Town."
Andover kid - "Uhhh actually Andover is A-Town...duh."
Anoka kid - "Uhh no. Anoka's the Real A-Town. You're just a rich kid who can't come up with your own title like we awesome Anokans can. Duh."
**(Andover IS mostly a well-to-do community so most people refer to them as such..not very nice but that's how this world works, right? Hate what we don't understand, are jealous about, and/or can't have? Sad but true because most of us are little high schoolers who can't grow up)
