Skintern

In American workplaces, a skintern is an informal term for a summer intern, usually female, who dresses in clothing more revealing than that which is common for the field in question.

The term is a portmanteau of skin and intern. It was first widely used about such interns working in offices of members of the U.S. House of Representatives in Washington, D.C. around the mid-2000s; Julia Allison claims it was used in that sense as early as 2000. Since then it has spread to other industries outside government and politics that also employ summer interns.
