[Ladyflipflop]

Hello,
Old lady grandma here and I'm confused about all the abbreviations, can you tell me what they mean please?
Like DH DS etc 😆

Dear/darling husband
Dear/darling son

There's a list here https://www.mumsnet.com/i/acronyms

DH - Dear Husband
DD - Dear daughter, same for son, Mum , dog etc
DSS - dear step son/etc
LTB - Leave the bastard
ODFOD - insult - a bit sweary

😆 thanks.

What does CF mean please - in the context of being clever/careful with money?

CF is cheeky fucker.

I wouldn't have got that in a month of Sundays - thanks!
