a clapback
When someone roasts you, and you hit them back with a roast so hard it makes them cry like a baby.
You said I was a failure? I said, ‘You’re a failure with a bad personality.’
He said I was stupid? I said, ‘You’re a stupid person who also has no idea how to spell.’
She said I was ugly? I said, ‘You’re ugly and also have no life.’
