Trigglypuff is the nickname given to a Hampshire College student who was recorded loudly protesting in the audience of a University of Massachusetts Amherst event titled "The Triggering," which featured a discussion criticizing politically correct movements on campus hosted by conservative vlogger Steven Crowder, Milo Yiannopoulos and Christina Hoff Sommers.
On April 25th, 2016, student protesters began loudly shouting at speakers during "The Triggering" event held at UMass Amherst, with many accusing the hosts of "hate speech." Among them was an enraged female student who was recorded repeatedly yelling while flailing her arms at host Christina Hoff Sommers. On April 26th, 2016, the campus news site Campus Reform posted an article about the incident and uploaded a recording of the event to YouTube, gathering over 786.000 views within 48 hours.
The following day, Redditor Herelam uploaded the CampusReform video to the /r/KotakuInAction subreddit, where many mocked the student protester for behaving erratically. In the first 24 hours, the post garnered upwards of 2,000 votes (93% upvoted) and 690 comments.
