I'm sure you've all had this experience. You've let out a deep belch, and a little something more than air comes up. I guess it's basically V because it'll be liquid, and taste very sour and acidic, sometimes even burning your throat. I can often feel little chunks of particles in it. I've never actually spit it out though because I'm afraid to see what it looks like and I'm sure it would look identical to V and I just don't dare want to look at it so I just swallow it back down.
So when this happens, is this considering v*ing in any way? Sure it doesn't involve nausea or large amounts, but your stomach is still sending v back up, right?
