I think it did. Some of my mates are various forms of squaddies, and they're pretty grim.

I've seen this sort of thing happen
There's an annual "Iron Man" competition at Newcastle Uni in Australia, but it's more "Iron Stomach". Contestants (usually already drunk) have to eat and drink all manner of horrors, such as pints of grated parmesan cheese, off lumpy milk, all sorts of nasty combos designed to churn the stomach.

The rules are basic: to win you must be the first to consume whatever is on the menu that year. If you vomit it up, it doesn't count as consumed.

However, you can consume the vomit to move on to the next item. Pretty grim.

Worse I've seen is one of the contestants mates (also very drunk) consume his vomit for him... technically very much against the rules, but was allowed for the sheer horror of it. I don't think his mate won though.
