A gender-neutral firefighter, used for fire service workers or, more broadly, to praise someone who 'saved the day' in a non-literal sense ('you're a real firefighter for fixing that bug'). Trivia: this and its gendered variants saw a huge spike in usage during major wildfire seasons (Australia 2019-2020, California recurring), used as tributes to first responders.
