Viva el Betis is the traditional rallying cry of Real Betis Balompié, the Seville football club founded in 1907 and known for its green and white colours and loyal support. Supporters chant it at the Benito Villamarín Stadium and shorten the club name to Beti in affectionate slang, which explains the spelling viva er beti. Clips of the shout spread on soundboards and social video as a meme, detached from full match footage and reused whenever fans want an instant burst of Betis pride.
