Viper's Bugloss 

Viper’s Bugloss is unusual as it is the name for two entirely different things:
1 A common European plant "Echium Vulgare" also known as Blueweed, which has rough, hairy leaves and the flowers start off pink but turn blue as they mature;
2 A European moth "Hadena Irregularis" which flies from July to August, believed extinct in the UK due to loss of habitat;
So despite sounding a bit sinister, it’s just the name of a couple of nature’s minor oddities.
"Oh look, Viper's Bugloss!"
"Which? The plant or the moth?"

Kentucky Viper Militia 

Inbred hillbilly murder mafia mostly known for fucking there cousins, going to prison, having a speech impediment and of course cooking meth and committing homicide. Favorite pass times of the kentucky viper militia are: Enjoying life in mental hospitals, getting drunk and lighting stacks of tires on fire in the middle of the street on new years and dancing around the fire hooting and hollering and shooting guns in the air and praying to demons. They can often be seen driving around in huge trucks running over everything from garbage cans to motorcycles and shooting while driving. You might ask where are they driving to? In most cases they are on their way to find more cousins to breed with. They own whore houses and strip clubs and they violently control their so called territory. When other gangs dont pay the extortion tax demanded by so called field commander members of the other gang usually end up in a shallow grave by the side of the road. Every whore house and bar they own is filthy AF and must be avoided for health reasons. People die in those places.
Daryll: Last night I went to a whore house that is ran by the Kentucky Viper Militia. One of the whores OD'd in her room
Brandon Junior: That's scary as fuck. Did anyone try to help her?
Daryll: No bruh. The chick croaked and they raised the price cuz they said you gotta pay more for fetish shit

More from Urban Dictionary
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.
