Shadowbag 

To place the shadow of one's testicles on the shadow of another's forehead

My wife fell asleep in the chair so I turned on a lamp in the corner and shadowbagged her.

shadowbunny 

A Shadowbunny is a virtual machine (VM) instance that is deployed on a compromised host to provide an adversary persistence and at the same time evade detections. The VM itself does not have any security monitoring and is entirely attacker controlled.

Ryan deployed a Shadowbunny during the red team exercise.

shadowboost 

The selective promotion of a user on a web platform without the public being aware of it. It takes the form of unrestrained, covert, and artificial advancement of an individual over others in order to give them an unfair advantage. It involves advancing posts, profiles, opinions, videos, streams and other content from that individual to much larger than average and underinformed audiences without their knowledge or consent. It's harmful in that it's underhanded, subversive, manipulative and diverts public opinion from truths.

<half-asleep guy>: Why is my feed so full of statistical and moral falsehoods?

<awake guy>: Don't you know? It's one of countless examples of thousands of years of shadowboosting.

Shadowcat

Kathryn 'Kitty' Pryde, one-time youngest member of the legendary mutant team known as the X-Men. Her power was known as Corporal Intangability, which would let her 'phase' her molecules through any solid object, effectively passing through it like a ghost. Formerly known by the code names 'Sprite' and 'Ariel,' she later went on to be a founding member of Britain's premiere superhero team, Excalibur.

Running as fast as she could, Shadowcat phased through the obstacles that got in her way.

shadowban

Banning a user from a web forum in such a way that the banned user is unaware of the ban. Usually takes the form of showing that user's posts/profile/etc. only to that user; other users never see them. Considered underhanded chicken-shit behavior.

Fark has turned into a bunch of shadowbanning pricks.

shadowfan12507 

Use this to describe someone who died to Boa Hancock in any game.

Person 1: How did shadowfan12507 die to Boa?
Person 2: Yeah it’s weird, he’s also really inconsistent in saying if he likes her or not.
Person 1: Who knows, maybe he died because he tried fighting her with one hand.
