Shanghaier is a term used to describe a person who forcibly or deceitfully takes someone into service, particularly onboard a ship, often for the purpose of working as a sailor. There are several synonyms for shanghaier, including dragger, press gang, crimp, and kidnapper. The term crimp is particularly associated with the Shanghaiing of sailors in the United States during the 19th century. While dragger and press gang generally refer to the act of forcibly taking someone, crimp and kidnapper can also encompass the deception and trickery often used to lure individuals into service. Overall, all of these terms carry a negative connotation and highlight the abusive and exploitative practices used to staff ships in the past.
