It overheated and started smoking while it was in the galley, and the crew chose to stop the smoke with a fire extinguisher. There were no flames at any point.
I believe this -- I just wrote fire at first because one of the pax near me was waiting for the bathroom when it happened and that's what he told the nearby pax when he got back to his seat. He didn't seem particularly freaked out and I didn't even see smoke (even at the back of the plane), so I figured the attendants likely had/would have it under control.
