Tchotchke
(重定向自Chachka)

A tchotchke (/ˈtʃɒtʃkə/ CHOCH-ka) is a small bauble or miscellaneous item. The word has long been used by Jewish-Americans and in the regional speech of New York City and elsewhere.
The word may also refer to free promotional items dispensed at trade shows, conventions, and similar commercial events. They can also be sold as cheap souvenirs in tourist areas, which are sometimes called "tchotchke shops".
