The word dumani is singular, referring to only one person. Dumanis is plural. The word consists of "Du ma", a very vulgar Vietnamese cuss word.
Dumanis are NOT to be confused with Vietnamese gangsters, Dumanis typically look/act "hard/gangster" in appearance but will never do anything or fight anyone by themselves. a Dumani likes to "mean mug"/stare at other Dumanis in a taunting manner. Dumanis are mostly seen in Northen California but also seen in areas with a high Vietnamese population such as Orange County, Los Angeles, Houston, etc...

Any person(s) with the similar characteristics that is any other race/ethnicity other than Vietnamese would be called a "their race" Dumani-lookalike (i.e.: Chinese Dumani-lookalike, White Dumani-lookalike, etc...)
Look at this Dumani fool right here, I think he has a staring problem...

You become unable to use all of your brain cells, which by extensions makes you dumb because you only utilize one or two brain cells. Basically, when a smart person is just dumb.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
