Spark Plug Blew Out!, projectile plug... what happened? Options

[Chrobis]

Well I was just cruising down the freeway the other day and all of a sudden I hear this noise, it sounds as if I just ran over something really big (but I saw nothing in the road) or like my engine was breaking to pieces and falling out of the car. So I freak of course but I stayed calm enough to pull to the side of the freeway and check my car out. I pop the hood and one of the spark plug wires is just laying over the intake manifold... First I think hey the plug came loose, no big deal, so I pop it back in but it dosnt connect. I start the car back up and it just gets popped back out. I determine the plug is gone and end up driving for awhile to where I was going without one cylinder firing, sounded like I was driving a really big lawnmower. So I pull it the shopping center where I was meeting my sister and then see the pretty sizable dent in my hood, going out if your looking at the top of the hood, paint was chipped and everything. I end up driving my rickity lawnmower down the street to a Kragen's. Well they dont have the same kind of plugs I have 3 left of so I end up getting 4 new ones as to not mix it up. Well I use their loner tools which suck and end up keep getting stuck in the damn engine cause the ball bearing releases before the rubber thing in the spark plug socket. So I go and buy a damn socket extension that will work for $10, way over priced for a stupid socket extension. Well then it turns out it wasn't just the loner extensions that suck, it was also the spark plug socket as well. So I walk back in to buy a damn spark plug socket, and no one is at the register so I just left with it, yes yes stealing is wrong... but so is charging $13 for a cheap ass tool! So I get the spark plugs back in and the cylinder that blew seems like the plug was having to much resistance when it got almost all the way screwed in, so I kinda left it possibly loose but I didnt want to strip the threads if they are already stripped. So I give back all the loner tools, and return the socket extension ;-) and keep the spark plug socket... yeh yeh its wrong I know. So I drive away and it seems to be running, but the check engine light is on (normal I thought, has to be reset) so I tell myself to get around to reseting it but a day or so go's by and it turns off itself.

So What I think could have happened was
1. it was loose and blew out when it sparked and had nothing to grab on to hence being ejected from the engine.
2. Timing is off and the piston was on the way up when it blew ejected the plug.
3. God Hates me and wishes ill but non lasting bad things upon me.

What else could have happened? Should I try to tighten the plug more? and How bad is it if the threading is stripped?
