Does it go "tick-tick-tick" when you try to start it? Then it's probably the starter.
I was getting a "tick-tick-tick", which is why I figured either starter or battery, and since I replaced my battery less than 2 years ago, I was figuring starter. It's the battery. Mixed emotions - I'm pissed because this battery seems jinxed (it was replaced on New Year's Eve 2011, sometimes referred to as THE WORST NEW YEAR'S EVE EVER, then had to be serviced again in late February because apparently it hadn't been connected right when it was installed), but at least it falls well within the "3 Year Free Replacement". So I have to orchestrate things so I can meet AAA guy at my mechanic's, but at least the battery will be free. And while they were poking around, the mechanic found a crack in my serpentine belt, so I get that fixed BEFORE breaking down by the side of the road. So I come out okay, losing a couple hours of work and substantially less money than I feared, just kind of a pain. But still, for a 16+ year old truck, it's been super-reliable and I shouldn't complain (because despite claiming not to believe in such things, I absolutely never want to tempt fate to take it away from me for being ungrateful).
Even google seems to have no idea on "Bohama teenie" - it thinks I meant the Bahamas. Very weird to have an elderly teacher come up with something so obscure for a weird insult. Def seems like you're well rid of her. And good luck dealing with those midterms.
Still no internet at home. Trying to stay up with stuff at work, but can't access email or Facebook from here. I shudder to think what my inbox is going to look like when I finally get back to my email.
