In military slang, a restroom is often called the head. This comes from shipboard tradition: the toilet area on a vessel was located at the head (the front/top area of the ship), so sailors used that term for the bathroom. The term has stuck and is commonly used in Navy and Marine Corps settings, making it the best fit for this question. The other terms aren’t used to mean a bathroom—inkstick and leadstick aren’t standard restroom slang, and whiskey locker refers to a place to store alcohol, not a bathroom.
