For those unaware, originally "oofy doofy" theory stated that women preferred ugly men over chads. The theory originally came from "hellbythedashboardlight" who is a morbidly obese man who lives in his car and claims to have a PhD, have been a professor at one point, and be good looking and that he couldn't get a gf because he was too good looking and successful and women liked poor broke ugly men. It's a reactionary theory meant to be antithetical to the blackpill. The theory because popular among a small group of rabidly aggressive contrarian autists who seemed to dedicate their lives to saying "OOFY DOOFY IS LAW!". That's another thing I noticed....everyone who unironically advocated for this theory was cripplingly autistic. The type where you could tell they're really "off" straight away.
ITV/rehab room took the term and successfully rebranded it so that it's now synonymous with "betabuxxer".
