You yell back at someone because they said something that felt like it was a direct insult to you.
'You're the worst.' 'The worst? So you're saying I'm a failure? I'm not even going to argue with that.'
'You're ugly.' 'Ugly? So you're saying I'm a monster? I'm not even going to fight you on that.'
'You're the worst at video games.' 'The worst at video games? So you're saying I'm a noob? I'm not even going to deny that.'
