I just don’t think a pre-packaged comeback (hilarious as many of these are!) can truly ‘destroy’ someone. It needs to be personal to the situation to really hit them deep. Unfortunately I can’t think of an example.

I refuse to play mind games with the unarmed.

There are people who did not stand at the front of the line when intelligence was gifted . But that guy wasn’t even invited at all…

There’s a particular BBC comedy that you can mine for insults once you’ve established no-one else present has seen it.

• He’s so dense light bends around him.
• As useless as a marzipan dildo
• As useless as lube at a funeral
• I’ve never seen anyone look so fucking ugly with just one head
• Do you know 90% of household dust is made of dead human skin? That’s what you are to me.
• Watching him work is like watching clown running across a minefield.
• He’s here, depriving a village somewhere of their twat.
• I’m like flypaper for dickheads today.
• Sorry I’m late. Traffic was an absolute bitch. No offence.

Still my favorite comeback, I use it fairly often
