a person living in close proximity to you(i.e. 2-4 streets away), which would make it easy to identify him/her as a neighbor, yet too far away to be an ACTUAL neighbor.
The name refers to the fact that everyone who is zoned for your bus stop lives within a couple of streets from you.
Bola: Yoooo, I live rightnext to him !
Lauren: really? is that your neighbor

Lauren: Ah, I gotcha.
My plane neighbor, on my flight to Dublin, was weird as hell. They clapped when the plane landed. I hope I have a more normal plane neighbor on my flight back.
