The fandom for 5 Seconds Of Summer. Short for 5SOS Family because we are not a fandom but a family. Everyone is loving to eachother. The boys of the band are Micheal Clifford, Luke Hemmings (lucas), Ashton Irwin, and Calum Hood all love the 5sos Fam. Easily the best fandom you can be in. It's a beautiful place with pizza,kittens,puppies,rainbows,and band merch. But at the end of the day Jack Hemmings slays the game.
