"Wedgie," a teenager's locker-room nightmare, has made it into the dictionary.

Webster's New World College Dictionary (search), based in Cleveland, said "wedgie" was among its new additions to its latest edition.

The new edition will carry this listing: "wedgie: noun. a prank in which the victim's undershorts are jerked upward so as to become wedged between the buttocks."

The dictionary also carries the traditional "wedgie" definition: a type of shoe.

"'Wedgie' was always a part of the high school terminology that you sort of never thought about later," said Editor in Chief Michael Agnes.

"It never really entered the mainstream until the '90s. It broke out of high school and, boy — if you don't know what it is, you're absolutely at a loss."

The new edition will reach bookstores by May and has 58 new entries, plus another 20 new senses of existing words (such as "wedgie").

The additions include "Al Qaeda," "blog," "cargo pants," "irritable bowel syndrome" and "partial-birth abortion."
