Dumbening 

A rare, genetic condition found in males, usually surfacing at the on-set of puberty; the result of which is a swift plummeting of the carrier's overall intelligence.

Young Abraham quickly went from smart as a monkey to dumb as a chimp, as a result of his dumbening.

Dumbing Down

1: The process by which products are stripped of depth and complexity in order to simplify them for the masses.

2: The removal of complexity for the purpose of mass appeal.

3: The homogenization of entertainment and media.

"Plots, Scripts, and Stories are all too complicated for the general masses. By dumbing down movies we can broaden their mass appeal."

"Thanks to the Dumbing Down of Spore many found the game to be uninteresting and unenjoyable once the initial gimmick wore off."

"The Discovery Network achieved higher ratings by Dumbing Down it's programming."

Dumbling-down 

Doubling-down on a dumb, stupid, idiotic comment.

Literally anything said by President Trump, to which he and/or his deplorable sycophants follows with an even more dumb comment.

First, Trump calls a bunch of countries shithole, then tried to deny it and now his followers are saying it's "bar-room talk". These morons are just dumbling-down on his vileness & racism.
