jacket
n.—Gloss: Richard Allsopp’s Dictionary of Caribbean English Usage defines this as “the child of a married woman and a man who is not her hustband” or “any child whose paternity is denied.” Note: The term is used in Jamaica and Belize. «According to reports, as much as 33 per cent of men tested were proven not to be the fathers of the children said to be theirs. To put it in popular parlance, these are the fathers who have received “jackets.” While it is a serious matter to any man so affected, the mere mention of “jacket” becomes a joke to others.» —“Sobering side of the ‘jacket joke’” Jamaica Gleaner (Kingston) Oct. 23, 2007.
