kumquat nightmare

Absolute madness. The peak of it.

e.g.
'Everything happened in 2020. It was a kumquat nightmare!'
'He's out of control. He wore Hello Kitty crocks to his grandad's funeral. He's a real kumquat nightmare.'
'Don't hire her. At her last job, she tried to climb a wall using only her lips. She's a kumquat nightmare.'
