Snicklefritz or Schnickelfritz is a Pennsylvania Dutch term of affection usually for young mischievous or talkative children.
Considering similar German terms, many larger bilingual German–English dictionaries include the word Schnickschnack, which is defined as chit-chat or tittle-tattle and nonsense. The Wahrig Deutsches Wörterbuch (Wahrig German Dictionary) indicates this noun is a doubling of Schnack which also means chit-chat and drivel. An informal verb, schnicken, means to jerk or seize, implying fast or choppy movements. Whether the aforementioned terms relate entirely to snicklefritz is not known, but would appear to be closely related in referring to a chatty or impulsive person. Moreover, the word (or nickname) “Fritz” is German slang for the names Friedrich or Frederick.
