They keep writing about food they find delicious and end the description with (and it makes my teeth hurt to write this) the words 'nom nom'.
Is this:
A) acceptable and IABU
B) unacceptable and I should gently suggest she perhaps use 'yum yum'
C) completely unacceptable and should be De-friended immediately?
I can be unreasonable about munching noises, I nearly came to blows with someone chowinh down on some crisps on a train once... and lost it with a co-worker who sat across from me and was attemting to eat carrot sticks quietly for an entire 3 hours - And that magnum advert where she but through the chocolate coating made me pathologically enraged. As does 'nom nom'.
