A "banshee" is a type of spirit that comes from an Irish legend. It's a female spirit the wails and screams at night, warning others in the house of death. Ex: She dropped her hot coffee and screamed like a banshee! Ex: I woke up last night and heard something that sounded like a banshee. I'm sure it was nothing.
