a BAND (not boyband cuz they play instruments) consisting of 4 australian 16-18 year olds. THEY ARE SEX GODS!!!! Their names are Luke Hemmings (vocals, guitar), Calum Hood (vocals, bass guitar), Michael Clifford (guitar, vocals), and Ashton Irwin (drums, guitar). They are as hot as frickin Tartarus, and their accents alone can just blow up your ovaries. Then their singing, oh my gods. Their singing is shamazing. Think of one of the best bands that all sing ever, then multiply that awesomeness by 1000. Yup, that good. they're commonly known as 5SOS.
"Did you hear the australian dudes that sing Try Hard"
"Omg yes!!!! 5 Seconds Of Summer is like the best band ever! Luke is sooo........."
They continue to fangirl till they die.
