Marble games, or pitch, are among the most widely played of traditional boys' games in Trinidad and Tobago and have declined in the last two decades. Nearly 200 marbles terms found in Trinidad and Tobago English Creole are documented. Although most are British in origin, there are East Indian, French Creole, and possible African influences on this lexicon. An analysis of the discourse of marbles talk in its sociocultural context was prompted by its strong positive affect for men who played pitch as boys. Using frameworks from the sociology of games and from studies in language and gender, marbles talk is shown to demonstrate features of masculine gender-linked use of language and games, including highly elaborated rules and strategies, and competitive and confrontational use of language.
