I finally got my computer (semi-) fixed and couldn’t wait to get on here and find out what all that CAW-CAW-ing was all about. We were thoroughly gobsmacked when she did it...twice if I’m not mistaken!
I think she meant it to be a “swan song”. But your explanation does add some context.
She made it so easy to cheer Simon on when he gave her a well-deserved dressing down. And then she went on to prove him impeccably right by delivering the worst performance I’ve ever seen from a top tenner.
Go. Go. Begone. We shant miss you.
I agree. We've heard some bad "swan songs" before, but Megan's had me reaching for the mute button.
