Goose pimples
From Tardis Wiki, the free Doctor Who reference
Goose pimples, also known as gooseflesh, were a natural reaction of the human body to cold temperatures or fear.
Sarah Jane Smith once disembarked from the TARDIS in February in England only to remark to the Fourth Doctor that "even [her] goose pimples had goose pimples". She then compared the temperature to that found in the Arctic. (AUDIO: Doctor Who and the Pescatons [+]Loading...["Doctor Who and the Pescatons (audio story)"])
