Domitillect

Domitillect is a word that means to have lots of intellect on a useless thing. For example, if you know every adjective known to man, you would have a LOT of domitillect. Domitillect is like Intellect, but instead of having just knowledge, you either have knowledge on something that’s useless or you have a useless bit of knowledge on something. This word comes from Hong Kong

Here’s an example of how it could be used in a conversation:
“Hey, I can name all species of cats in 30 seconds!”
“You have so much domitillect!”
Or for having useless information about something:
“Hey, did you know that your cat can purr 2x louder than other cats and can hear way better than you?”
“Okay, but that’s just domitillect!”
