title troll

someone that often makes jokes with ideas come from the title of something (often videos).
Like patent trolls, they don't produce any original material, but makes the ecosystem more toxic.
example:
title: Why are we not using graphene in our electronics
joke: I once try to buy graphene at the fish market, but all i get is seaweed.
title: We let our food mold and eat it
joke: I eat molded cheese for breakfast to increase mobility.

Sigh, the comment section is full of title trolls, where are those that actually have context.
