A band from Australia who enjoys teasing their fans and seeing them go crazy
"Lol 5sos got us all hyped for nothing"
"Yeah, isn't 5sos the band who enjoys seeing their fans go crazy over nothing?"

A shitty boy band that thinks their punk/pop punk/emo but are just posers and girls obsess over them because they think they are edgy for listening to them. They also think they are the the new mcr but no one will ever be the new mcr
P1: Man 5sos just makes me want to punch people because their music is so violent

P2:name one song that isn't about girls

P1: .....
P2: listen to some bmth if you want violent

P1: I think that 5sos is like mcr and they're violent

P2: okay so mcr is violent but they don't sing about girls all the time unless it's Helena witch is about gee and Mikey's grandma
P1: ....
P2: plus how the hell is 5sos violent

P1: .............
P2: that's what I thought

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.
God the 5SOS Fam is the most supportive fandom there is. I love the 5sos Fam so much♥
