Scanless

A word your mum or nana uses.
People say this when they find your behaviour unreal in a bad way, or stupid.
It also means pointless

You and your brother arguing over who has the bigger balls, “fucking hell this is scanless yous are idiots”
Your nan tries to read a magazine and yous 2 interrupt her by arguing. “What the fuck are you doing for fuck sake this is scanless this behaviour”
