What does it mean if a girl shows you her panties?

Oh, dude, if a girl shows you her panties, it probably means she's doing laundry and accidentally dropped them in front of you. Or maybe she's just really bad at keeping her clothes in check. But hey, who knows, maybe she's trying to send you a signal, like Morse Code but with underwear. Just remember, consent is key, so don't go jumping to conclusions like a kangaroo on a trampoline.
