A person or persons for whatever reason have slipped to the bottom of the species intelligence grid. Possibly caused by head trauma, gestational drug use, binge drinking or simply genetic abnormalities most likely incest... Can be affected at any age and almost always permanent. The world is full of rum dumbs and nobody is policing the gene pool unfortunately!!
Oh no! Leroy fell on his head when he was younger and now he rides the short bus with the rest of the rum dumbs.

Get the Dumb Twinkmug. Named for Patient Zero, this illness was first discovered in Washington DC in 2011. Categorized as a special kind of stupid, this malady directly affects the IQ and causes it to drop to under 60 points. Symptoms include feigning expertise on an unfamiliar subject and the ability to verbalize nonsense.

Get the Rand Dumbmug. An authentication card that contains digital user data, such as a personal identification number (PIN). An example of this is usually an ID, ATM card, or any card with a magnetic stripe.
My dumb card has a black magnetic stripe that contains a digital encrypted pin that is compared to the pin I enter on the ATM.
