little bum! what did you say back to him??
You probably don't want to know what I said back to him. Wasn't very "good mummy" like

Manhattan - you could be onto something. I told DH via email what he said and he said back "What!? That is pretty weird....sounds to me like something he has overheard from older boys at school. When he said to me the other day he was going to cut me, I asked him why he was saying that and if he heard that at school, and he said yes the older boys were saying it. So I think he has added the ‘boobs’ part cos he always craps on about boobs. "

And yes he is totally obsessed with boobs.
