Placeboism 

Placeboism was founded by freakbymistake and drink_u_pretty_ to honour and worship the band, Placebo. We believe in polytheism because we worship THREE Gods: Brian Molko, Stefan Olsdal and Steve Hewitt

Dear Gods that are Placebo please make my mother buy me your album for my birthday

Placeboi 

A male fan obsessed with the English rock band Placebo. Especially Brian molko.

Placeboi's usually dress in black and wear eyeliner. They unabashedly wait hours to be front row at placebo concerts.

placebocism 

first introduced by J.M. Jones a New England based paranormal investigator it is an exorcism ritual perfomed to remove a demon where non is actually present using instead the deception to cure a client.

With no demon actually present we prepared the room for the placebocism.

placeboing is when you take something you think is a drug, but isnt, and instead of tripping on a drug you trip out because your brain thinks you took a drug. causes anything from mild paranoia to city-wide power outtages.

Placebism

The Placebo Effect version of Debunkism—the ideological commitment to explaining away any phenomenon, experience, or reported effect as "just the placebo effect," regardless of evidence or context. Placebism treats "placebo" as a magic explanation that ends inquiry: it's not real, it's just placebo. The fallacy lies in using placebo as a dismissal rather than a phenomenon worthy of study. The placebo effect is real, interesting, and powerful—but Placebism uses it as a cudgel to avoid engaging with claims that challenge materialist orthodoxy. It's skepticism that has forgotten to be skeptical about its own explanations.

"He meditated and felt better. Placebism says: just placebo. Acupuncture helped her pain. Placebism says: just placebo. Thousands of years of healing traditions? Just placebo. Placebism uses 'placebo' like a magic word that makes experiences disappear. But the placebo effect is real—and using it to dismiss everything is ideology, not science. Placebism explains nothing; it just explains away."
