firehose - propaganda delivered quickly, repetitively and continuously in high quantities via multiple channels, with no commitment to objective reality. (Defined by C. Paul and M. Matthews for Rand Corporation in "The Russian 'Firehose of Falsehood' Propaganda Model")
Over the past three months, the administration has continued firehose, making numerous false claims about the press and repeating assertions clearly proven untrue.
