-Colloquial geek: someone who likes geeky stuff and does it for fun

-Circus geek: addict who debases themselves at a carnival as a job

-Internet troll: someone who bothers people on the internet for fun

I started with a joke conflating colloquial and circus geeks. What is the shared "blackness" of these "kitchen apparatuses" here? That nobody really wants them? Why did you decide my joke was a good place to reply with social commentary about internet trolls??
