Totally Not Vegan. Used to describe a food item or situation that is not vegan. Came into common usage after the (terrible) webcomic Totally Not Vegan.
John: This is a great potluck. What's in the casserole?
Kim: Oh it's TNV, there are eggs in it.
John: Gross, that shit is nasty.
Kim: Yeah, fuck eggs.
Kim: Oh it's TNV, there are eggs in it.
