It's when someone just up and disappears on you without warning, only to reappear again and then to vanish as mysteriously as before. These peoples are ghosts. They regularly take up ethereal form & inexplicably disappear all lickety-split-like without notice and return to corporeal form when least expected. Named after YouTube personality Natalie Tran who is as reliable as tits on a fish. LOL.
