An amazing Australian band that plays pop-rock music. The full name of the band is 5 seconds of Summer but they are known as 5sos. It consists of Calum Thomas Hood, Luke Robert Hemmings, Michael Gordon Clifford, and Ashton Fletcher Irwin. This band is NOT A BOYBAND (if you think they are search up the definition of a boyband.) All four of the boys in the band are cute, adorable, and nice. They love their fans to death, and they never let the fame change them. They've been nice lads since the beginning and they still are. They're one of the most loved and popular bands ever!!!
Hey, have you heart of 5sos?

Yeah, aren't they the ones who sang the song She Looks So Perfect (slsp)?

Boyband. DO NOT BY ANY CIRCUMSTANCE CALL THIS BOYBAND A BAND. There are obviously 5 members as the title of this boyband is FIVE stilky odd sexies. They all are horny all the time, and the age of the members varies from 11 to 89. The songs are mostly about gay relationships, hairy vaginas, and dick popping sodas. 3/5 of these members have also had past carrieers in the porn industry.

Luekas Citremmings: 89 years old vocalist, never hits any notes, and always wear his hair down. Married to his guitar which he does not know how to play. Father of the boyband.

Calvin Hoodie: 14 years old asian, taking a part in the porn industry. no further information needed. Teenage dirtbag of the boyband.

Michael Angelo: Drag queen. Used to be actively involved in porn, 16 years old, never laughs and pink is his favourite colour.
Teenage fangirl of the boyband.

Ashtinio iRWINIa: Gay, 11 years old drummer. Married. Plays on his plastic drumset.
Baby of the boyband.

Ketchup: Noone really knows Ketchup's age. Plastic dog, the biggest porn star in 1987 though his fame has sunken since then.
Porn star of the boyband.

A band of four idiots who claim to be "not a boy band" (yes they are). People assume they are punk because they listen to Nirvana,Green Day,Blink-182,etc. But if they were really "punk rock" do you think so many directioners and beliebers would love them.Half of them didn't even know who Blink-182 was until 5sos came.
Stupid Fangirl: OMG!!5sos is playing tonight.

Person: Bitch get out of my face.
