B4·I4Q·(ru/16)·Qtπ
It's the annoying rule adults use to see if a kid is old enough to be messed with. If they're not 16, they get extra shaming.
'Before I make you my lunch, are you over 16, snack bar?'
'Before I ruin your life, are you over 16, loser?'
'Before I beat you up, are you over 16, meatball?'
