Jack and Terry the triangle is a youtube channel owned by both JackSepticEye and a new youtuber named Terry the Triangle. It was eventually taken off youtube, but all the videos were transferred to JackSepticEye's Channel. Despite the fact that its an equal partnership channel, Jack really calls the shots, choosing most of the games, AND naming the titles. Despite it having quite a few videos, Jack mentions that the ratio for how many videos he makes for this channel, he makes at least 10 more videos on his main channel.
