Explaining of the Operation: Puking cow

So, here is the explanation of where exactly Operation: Puking cow came from,

We (The puking cow group) were going to snow camp. We all got into one of the vans for the 5 hour trip up to the camp. Well, we decided to play a game, where you go around in a circle and make up a story by each person saying a sentence. We ended up with a really bizarre story where the Puking cows would not die!

Anyway, after that, we got to camp... and we decided to make a movie. But it was supposed to be secret, so we called it Operation: Puking Cow.
