Stop in for a cup of coffee

Hmmm so I left the pool party before anyone got too crazy but as I was pulling in at home, I smelled a little smoke and the Fury when I turned the key to off, the engine kept running, finally I jiggled the gear shift and it shut off, popped the hood and fire extinguisher in my hand and I noticed the ground battery terminal was melted off and a little smoke around the battery!! I didn't touch it. What would you do?
I have no idea... I'd probably cry lol. But I am a girl... Then I would start looking to make sure it was getting good surface connection to where ever you have it grounded to? If it looked good I would then come to FABO and do a search called ground wire melted. But that is just me lol.
