a wikipedia junkie
a person who thinks they're smart just because they can go from 'tree' to 'moon' without getting distracted by a random fact about a guy who invented a new type of sandwich in 1987
I tried to go from 'book' to 'alien' and now I'm arguing about which sandwich is better.
I started with 'fish' and now I'm reading about how a fish became a king in 1423.
I clicked one link and now I'm explaining the history of socks to my dog.
