Solaire of Astora is a fan-favourite knight from Dark Souls, the 2011 action RPG by FromSoftware, known for his sun worship, the 'Praise the Sun' gesture, and his cheerful invitation to 'jolly cooperation' when players summon him. His earnest optimism made him a mascot of the series' co-op community, and the phrase spread through summon signs, fan art, and memes about struggling players helping each other. The clip endures because it distills Souls multiplayer into two warm words.
