Sean William McLoughlin was born on February 7, 1990. He is known on YouTube as Jacksepticeye. He is "the most energetic [video game] commentator on YouTube". Jack refers to himself as the last remaining Bossatronio from the planet Bossatron. He does various series on games, where the episodes of a particular series are spaced out with 3-5 days in between, normally. Some series' Jack does are The Sims 4, Subnautica, and Happy Wheels. One of the two non-video-game series he does is "Reading Your Comments," where he responds to people's comments on YouTube and Twitter. He calls himself and his fans bosses, but always refers to himself as the superior boss. He does not have a name for his fan base because he recognizes his fans as individuals, not one.
