Undershorts, also known as underwear shorts, are a type of undergarment worn beneath outer clothing, particularly by men. There are several synonyms for undershorts, including boxer briefs, boxers, briefs, trunks, and compression shorts. Boxer briefs are similar to briefs but have longer legs, while boxers are loose-fitting, typically with a button fly. Trunks are shorter than boxer briefs but longer than briefs, and compression shorts are worn to provide added support during exercising and sports activities. Other terms that may be used interchangeably with undershorts include underpants, undershirts, and intimate wear. Regardless of the terminology used, undershorts serve an important purpose in providing comfort and support for the wearer.
