A discussion board I used to be part of had a catchphrase, "Be a f'ing human." A bit crude, but it's a catchy phrase that puts me in mind of having human decency and respect for others. So when I see a celeb branded a hero for checking on someone who fell in front of them, that falls under "be a f'ing human". It's not special, it's just being a decent human. Pounding on doors to make sure people get evacuated because of spreading wildfire, on the other hand, is squarely in heroic territory, in my opinion.
