Translation: "Not one of those Liberal Veggieweenies"!
It reminds me of this, which I love:
One of my best friend’s little sister wore a T-shirt that said the same thing, only substituted “kids” for “grandma”. Laughed my head off when I saw it. We’re all getting up there, so it was nice to see that someone else still cares about punctuation. Did I mention my friend is an editor for a professional newsletter/magazine? I bet she gave that shirt to her sister.
