short hairs

short hairs

The hairs on the back of one's neck, though it is often (and incorrectly) assumed that the phrase refers to pubic hairs. Typically used in the phrase "have (one) by the short hairs," which means to completely control, dominate, or hold power over someone, especially in a difficult or awkward situation. Did you see that poor intern running around earlier? The boss really has him by the short hairs.See also: hair, short
