I feel like more people should know about the Filipino phrase bahala na si Batman. quite literally, it means it's up to Batman. on a more figurative level, it means that you're leaving something to God/fate - metaphorically represented by Batman, of course.
big event that you haven't prepared for but you're going anyway? bahala na si Batman. major exams coming up and you haven't reviewed yet? bahala na si Batman. about to do anything remotely risky/luck-based? bahala na si Batman.
anyways, I just think it's hilarious that Batman is now a part of our culture through this saying. is this a thing in other cultures/languages too? let me know!
