Someone who uses the stall next to you, especially when you both are taking shits. You'll meet each other, stink, and part ways.
"Damn, how long were you in there?"
"I don't know, I was talking to Mike."
"Who's Mike?"
"He's my dump neighbor."
"oh..."
"I don't know, I was talking to Mike."
"Who's Mike?"

A neighbor or group of neighbors that aren't pleasant to live near. Usually loud obnoxious drug addicts who don't have any consideration for the people they live around. They are loud and unruly in the late hours of night and early AM hours. You get a stroke of luck where you suddenly don't see them for a few months. They might have been sent to jail or elsewhere, but you're just glad they're finally gone and that you can live in peace. But then they suddenly come back out of nowhere, back to their old antics and habits. You then realize their absence was temporary - thus the term "boomerang neighbor."
A neighbor you wish would move elsewhere, but they always end up coming back somehow.

Crap! Is that Courtney pulling up outside? She's the boomerang neighbor! And here I thought we were finally rid of her...

A game where one drives a muffler deleted car through neighborhoods past 11 pm attempting to wake the sleeping individuals. You win the game if the person comes out of their house, chasing you.

When having sex with someone in the dark next to a window. While in the middle of the act you switch roles with one of your friends, well she is looking out the window-your waving 👋🏾 to her while being fucked by your friend,that she didn’t know was there.
The friendly neighbor -We perform the friendly neighbor now we are all friends without her knowing we are all friends.

The worst thing that has ever happened to you. Responsible for many sleepless nights and unproductive days. Will not stop shitting on your lawn. Will not stop attacking you when you’re just trying to walk in the neighborhood. Worst of all, he’s the one who got your 6 month old Yorkie pregnant.
My life has been a living hell ever since my neighbors got a dog. The neighbor’s dog has messed up many aspects of my life. I can’t sit in peace in my own yard.
