When you are fucking your lady and you take her vibratior and put it in her ass and turn it up to level 10. The sensation of the vibrating against the membrane between her ass and her vagina will shake like the neighbor next door having a rowdy party.
The person who’s number is identical to yours besides the last number which is one up or down. When you text them they usually get really pissed off really quickly.
To have sex with your girl by the window and half way through switch with your neighbor without her noticing, running outside the house and looking into the window and waiving at your girl.
Miguel: My girl was suprised when she saw me waiving at her from outside the window.
Mike: Yeah, we totally pulled a HappyNeighbor on her.
