This word has two faces. The literal one is just doing something backwards, like walking `patalikod`. But the one that stings? That's the figurative meaning. It's the "taksil sa likod" move. When your "friend" talks trash about you the moment you leave the room, that's a `patalikod` attack. It's the classic "plastikan" culture, smiling at your face but holding a knife behind their back. Hugot level: 100.
