MLMsplain
When a multi-level marketing consultant "teaches" someone—often a person more educated in the given subject—how their MLM product will magically cure their affliction, with questionable or non-existent scientific evidence to back up their claims. The explanation often incorporates scientific phrases that are randomly strung together and ultimately showcases the mlmsplainer's complete ignorance of the topic. "It like, changes the pH of the mitochondria and helps cleanse your gut at cellular level."
"When I confided in Karen about my best friend's recent diagnosis, I didn't expect her to MLMsplain how their therapeutic grade essential oils would cure his prostate cancer."
