Learn English – What does “doing five to ten for one thing or another” mean

From the Urban Dictionary:

1. “Camp” n. or “Campy” adj. refers to intentionally exaggerated thematic or genre elements, especially in television and motion picture mediums. “Camp” style willfully over-emphasizes certain elements of the genre or theme, creating an almost self-satirical milieu. Some of the most popular examples include the James Bond films (exaggeration of espionage activities) and the original Batman series starring Adam West.
2. Being so extreme that it has an amusing and perversely sophisticated appeal.
3. adj. overacted or exaggerated (sometimes purposely),

Jamming into one's throat means to make absolutely sure the person hears you and cooperates with whatever you're jamming into his throat.

So the captain, Pat Rafter, is saying that he'll make absolutely sure his team gets the message that they can't afford to be complacent when playing against the Chinese. They've got to be tough, or they won't win.

And the point made in the other example is that most vegan/vegetarians don't force their views on everyone else, or even look down on others, as some people seem to think.

If you're planning to use this expression, consider a more common form: "shove down one's throat". This NGram illustrates that "shove down his throat", though rare, exists; whereas "jam into his throat" does not even appear. (The same goes for "their throats", and, I assume, all other forms.)
