A traveling geek is an oxymoron. Geeks live in caves harassing the world from the safety of their own home. Well, it's safe until the consequences of their actions come knocking on the door. I guess at least you feel like you can outrun your problems while you're flying.
What you're describing is called an internet troll.
I'm unsure whether geeks often travelled with the troupe, though. Men hopelessly addicted to drugs were probably desperate enough for money and easy enough to come by that you might not bother dragging one with all the other performers. Especially since addicts tend to behave unsettlingly and steal stuff to feed the addiction. Talk about local talent.
-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??
What belies your joke is a kernel of truth. As they say, "birds of a feather...". Posting in a forum that facilitates social commentary implies that you should expect a social commentary when you post on this forum. Any other questions?
