From Yiddish: Knickknacks, collectables, figurines. Small figures and mememtos that can be bought at gas stations, dollar stores, gift shops, tourist destinations, etc. These are usually used to give to friends or to decorate cubicles. Sometimes placed in curio cabinets and so forth.

Steiner: Yo I heard you went out with Billy last night!
