Car overheated and coolant shot out?

I own a 89 Ford Probe GT. I had my car sitting idle at the store while i ran in. I come out and theres smoke coming out and the oil temp gauge is at the top. I turn off the car immediately and i hear what sounded like something burst and a crap load more smoke shoots out. I look around the car and there is coolant everywhere under the car and some sprayed out of the front through my intercooler and what not. I opened the hood to try to find where it was from but couldnt really tell.. Ive had a small oil leak for a while that has gone unaddressed so there was also oil on the engine but it looked like more than usual, so some oil might have shot out as well. What could this be? I was only a couple blocks from home so I waited a while then drove home and saw the temp slowly start to rise.
