I have you all beat. (Why am I saying that like I'm proud? :dunno
At the time this happened, I was 13 or 14 years old. I always used to hang out with my neighbor, who lived about 10 houses down the street from me. Well, they had recently gotten a puppy, Murphy, and it was really friendly and reeeeally playful. It was the kind of dog that you could push around a little bit, in a playful way, and it would enjoy the "fight".
Well, one day, I was lying on the floor and the dog kept trying to play with me. I wasn't really up for it, so I kind of pushed him away...but he kept coming back. So I finally gave in and started playing with the dog. For some fucking reason, I thought it would be a good idea to toss the dog into the air, like you would a baby. So, while still lying on my back, I grabbed the dog like it was a baby and started playfully tossing him in the air. Well, after one of the tosses, as the dog was coming back down, it's stomach landed on my thumbs and it made the dog throw up...INTO MY MOUTH.
OH MY GOD IT WAS SO SICK!!! It was all white and foamy, and the only thing I can remember after it happened was that I sprinted down the street back to my house going "EEWWWWWWWWW, EEEEEEEEEEEWWWWWWWW", with my arms flapping around like a little girl.
God, I can still taste it.
