fad syndrome
A disease you think you have just because you saw it on a social media post and now you're too proud to admit you're wrong.
My brother says he has 'gut microbiome' and now he takes 10 probiotics a day.
She posted a video of herself doing 'detox' and now she's famous for it.
He thinks he has 'infrared sauna' syndrome and now he sits in a hot box every night.
