ladder of humiliation
Roast is when you're meaner than toast. It's like you're roasting someone over a fire, and you're doing it with both hands. You're like 'You're so bad, I'm going to roast your face off.'
'You're a total disaster!' 'You're a disaster who can't even be a disaster properly!'
'You failed again!' 'You're roasted!'
'You're the worst!' 'You're the worst of the worst!'
