Shadow Argument

Making up a scenario in your head that makes you mad then complaining about it to others like it actually happened almost like shadow boxing but for neckbeards

"Yeah I understand the appeal of shows like Naruto and one piece, but the fanbases compare their show to shows like berserk as if they're close." (has never seen anyone do that therefore, shadow argument)

Shadow Shifting

The process by which something gradually fades from visibility or awareness—not because it’s gone, but because it’s operating beyond the range of detection. Still present. Still active. Just no longer seen.

"After the black hole collapsed, the surrounding radiation didn’t vanish—it began shadow shifting into the background curvature of space."

The one being shadow cancelled does not know this is taking place to undermine their professional career.

My boss and director recommended my for promotion, but HR vetoed it-I'm sure it is due to me being shadow cancelled so I can't advance.
