Kool-Aid
[from a kid's sugar-enriched drink in fruity flavors] When someone who
should know better succumbs to marketing influences and actually
begins to believe the propaganda being dished out by a vendor, they
are said to have drunk the Kool-Aid. Usually the decortication process
is slow and almost unnoticeable until one day the victim emerges as a
True Believer and begins spreading the faith himself. The term
originates in the suicide of 914 followers of Jim Jones's People's
Temple cult in Guyana in 1978. What they actually drank was
cyanide-laced Flavor-Aid, a cheap knockoff, rather than Kool-Aid
itself. There is a FAQ on this topic.
This has live variants. When a suit is blithering on about their
latest technology and how it will save the world, that's `pouring
Kool-Aid'. When the suit does not violate the laws of physics, doesn't
make impossible claims, and in fact says something reasonable and
believable, that's pouring good Kool-Aid, usually used in the sentence
"He pours good Kool-Aid, doesn't he?" This connotes that the speaker
might be about to drink same.
