AIBU to think that calling a 15yo

[AnonButRegular]

A slag is unacceptable, especially coming from a grown woman?

Who happens to be your daughters boyfriends mother

[Lookslikeimstuckhere]

I think that's unacceptable too. What a cow. She's best off out of that relationship!

[Bowlersarm]

Yep, not good OP. what happened?

[MarchEliza]

Bad. Really bad. (YANBU)

[ChoochiWoo]

why is she calling her a slag? did she cheat on her son?

[usualsuspectsparkly3]

It's unacceptable to call any woman or girl a slag.

[WooWooOwl]

It's not very nice, but when I was 15 there there were a lot of girls around who were indeed slags given the meaning of the word.

You might be better off concentrating on your dds relationship and the reasons for there being animosity between herself and her boyfriends mother rather than focussing on the use of the word slag.

[FrauHelgaMissMarpleandaChuckle]

Totally out of order.

[Whereisegg]

Yanbu How do you know she said it?

[Pumpkinpositive]

Of course it's wrong.

But you haven't given any background to this story, so no one can say exactly how wrong.

[usualsuspectsparkly3]

Just the girls who were slags then, Woo?

[madsadbad]

My language is terrible, but I hate and don't use words such as slag, slut etc.
Any person calling a person them is a nobber, but an adult calling a child them is sickening.

[madsadbad]

Of course usual you know them lads, just being lads, sewing their seeds, doing what lads do...

[PortofinoVino]

She's best off out of that relationship! said Lookslike.

Why? He may be a perfectly respectable, hard working lad, who has managed to drag himself out in a good way despite his mother

[lem73]

There is no need to hear a background story. It's an unacceptable word used to judge women for their behaviour made even worse when there exists no male equivalent.
I suspect this was just hurled at the op's dd as a casual insult rather than having a basis.

[DoJo]

when I was 15 there there were a lot of girls around who were indeed slags given the meaning of the word

Stony waste matter? Or girls who had sex? And what about the boys they were having sex with?

[squoosh]

It's never reasonable to use the word 'slag' against any female.

Her boyfriend may be lovely but at only 15 years of age she's better off out of a relationship where she has to deal with a person like his mother.

[SlimJiminy]

YANBU. Never an acceptable word.

[AnonButRegular]

There was an argument between the bf and his family. Dd was on the phone to him, his mother said he had to get off the phone because dd is "just some fucking slag"

[AnonButRegular]

Nope, dd is not cheating on him and has not cheated on him. They spend every spare moment together and clearly love each other - she'd do anything for him.

He spends so much time here, I treat him like my own, he's a lovely boy.

[Whereisegg]

Bloody hell op!
is your dd ok?

[AnonButRegular]

Dd is really upset

[AnonButRegular]

I think PortoFino hit the nail on the head - he's lovely, polite, respectful, helpful, is brilliant with dd. I have no qualms about him.

[Lookslikeimstuckhere]

squoosh has explained my point for me, thank you!

I am willing to change my view if it turns out he defended her to his Mother. Although I still maintain she would be best off out of the situation OP has described, given her age.

[LadyLuck10]

She sounds absolutely vile. She wasn't even there i would be fuming!

[Whereisegg]

Well his mum has done a great job of pushing her son towards your family.
