Why are you here?
Better disappear
This isn't a good site if you're under 18
Definitions all written while on caffeine
I'm not gonna lie
Gonna say it applies
I'm writing this as I sip on my diabetes
I mean Starbucks, sorry sweeties
But the point is DerpAnimation is some guy
He makes random animations on the fly
He's some stranger on the internet

He might like some things that get you upset
You don't know him and he doesn't know you
So don't search him up on Google, Bing or Yahoo
Person 1: Wow, he got attention for making trash?
Person 2: I think that's DerpAnimation
Person 1: Ah, makes sense

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.
