When someone has (a) pointed ear(s), like spock.
If you look at James from his right, you'll see his spock ear.

Large, pointy ears, whether real or used as part of a Halloween costume. Taken from Mr. Spock, the Vulcan science officer from the classic "Star Trek".
That guy must be a Trekker. He always wears Spock ears to every Halloween party!
