Nightbutt 

A term used to describe Nightbot on streaming platforms like Twitch. When this chat bot behaves in a way that is unintended or becomes irritating at times during live streams, the bot's name quickly becomes Nightbutt. Aside from being a butt once in a while, it's a solid tool for live streamers by providing a wide range of features for moderation, automation, and entertainment.

Oh, come on, Nightbutt, you're acting up again. Nightbutt, why are you being mean to Bob? Bob's just trying to use some emotes in the chat.
