Update: the #InfinityTrainHBOMax trending party on May 25th has been cancelled!
(The rest of the thread goes into a discussion of Dennis' involvement with trending parties, which, while also important, are not really relevant to the trending party itself. You can read the whole thread here)
Owen Dennis has said that the trend is canceled, but the op of the tweet itself has not said anything, as they are probably asleep (time zones).
However, there are plans to do a trending party on June 27th!
