TriHard is a long running Twitch chat emote that viewers spam during hype, awkward or tense moments, and pairing it with a 7 is widely read as a salute. Clips built around it circulate as in-jokes between streamers and regular viewers, often as fake donation or text to speech messages aimed at a specific username. This version is tied to the name Iforgotmynamealt, which gives it the feel of a personal callout that outsiders still use as a generic drawn out reaction sound in chats, servers and edits.
