When an individual has a 'gut feeling' something bad is going to happen without there being any sort of reason for them to believe that. This would also be used to describe when someone randomly gets the goosebumps or chills out of nowhere.
"She is such a Maddy thurley
"I know, the other day she said something about best Ed on the bus"
"What the hell she still watches that"
"Yeah, shes such a Maddy"
