Marbles games (“pitch”), perhaps the most widely played of all traditional boys' games in Trinidad and Tobago, have declined precipitously in the last two decades. This article documents close to 200 marbles terms found in Trinidad and Tobago English Creole. 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 high affect for men who had 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.
