Had a conversation with my daughter about this tonight which went as follows.
Me - you know that like and rate thing on facebook, would it be bad if somebody said someone was hot?
Daughter - no, it's fairly common
Me - would it mean that person fancied the person they were commenting on?
Daughter - no, it would mean they're not ugly, they're ok, acceptable
Me- would that be the case regardless of gender?
Daughter - yes, it's just a compliment to your pals
Me- would the person saying it be likely to get bullied or get a reputation?
Daughter (with a bemused look and a laugh) - no
Me - would the person saying it be seen as a slapper
Daughter (horrified look) - NO!
I think you need to realise that words change meaning and become diluted over the generations. Your daughter was not being provocative. If you are worried about her being bullied,you might want to start by looking at your own language towards her. I know you are concerned and trying to do your best by her - but that sort of thing is only going to make her resent you and become secretive. That will make it harder for you to protect her. Try talking to her and her friends, learn the lingo and then you can figure out whether it's something that needs watching or not.
