The absolute worst TwitchCon event in the face of history. Everything was a disaster. Two people got severely injured after jumping into a poorly-padded ballpit. Twitch got two of the streamers' pronouns wrong and refused to correct it. Spaces were too overcrowded. And many of the attendees were generally lacking in common sense and respect for others, with some of them even stalking a CC into their hotels.
Pajama casual is a term used when working from home and preparing for a video conference. All business above the waist and your pajama pants down below.
