The abbreviation of 'yoghurt on a stick', commonly used to reference people of a weird, odd or slightly eccentric disposition.
This saying is derived from the 2014 'Yollies' advert whereby, after being called weird, a yeti rebukes the Yollie with 'I'm weird? You're a yoghurt on a stick!'.
'That guy has a mullet and a waistcoat, what a YOAS'.
