2002 Honda Accord LX with V6 engine is overheating and leaking antifreeze?

Car was fine 2 days ago, but yesterday I was parked (car still running) & it was leaking antifreeze like crazy. Called my dad & he said it might be from using the A/C, and to just throw some more antifreeze in there and it should be fine. Long story short, car ended up overheating & after letting it cool for a good 30 minutes I tried putting some more antifreeze in it. Antifreeze just POURED back out coming from the front passengers side. I know it can't really be diagnosed without looking at it, but I haven't had a chance to yet. I was just wondering if anyone has any ideas of what it could be? I'm hoping it's just a hose & not my water pump or thermostat.
