nextdoor 

An app and social media website for people to talk about their neighborhoods. It's mostly filled with boomers complaining about shit that doesn't matter and that one really passionate guy that cares about everything. Its most useful feature is a marketplace type section to list things you are selling.

Gotta get my mom off nextdoor, I don't think it's healthy for her.

Nextdoor Syndrome 

A behavioral disorder in which one determines anybody and everything is suspicious and troublesome. Usually accompanied by an increasing hate for the homeless community, city council members, and airplanes flying at night. Syndrome generally occurs after joining Nextdoor.com, a social media website.

Codename: Kids Next Door 

A TV show about an organisation of children devoted to fighting teenage and adult tyranny with 2X4 technology weapons. One of the best old-school cartoons around because of its deep and detailed worldbuilding, extensive and well-developed characters and great plotlines. The kids live in treehouses, in 'Sectors' of about five operatives, and have assigned codenames; eg. Numbuh 1, Numbuh 2, Numbuh 3, Numbuh 4, Numbuh 5, who are the main characters in the show. They fight villains such as father, the Delightful Children From Down The Lane, Knightbrace, and Count Spankulot, as well as many others.
Though this show has been off the air for a number of years, it has maintained a fanatical following, who I am proud to be part of.
