I am sure I did this face
to the Mum in the playground who said it to her DD.
We were talking about a party and her DD wanted her attention so she kept tugging at her Mum's skirt. The mum said in a laughing voice 'Are you being an attention whore again Millie? Then she giggled.
Even if she was laughing its a horrid thing to say imo.
AIBU.
