kibitz : (KIBB-its)
1. To look on and offer unsolicited, meddlesome advice.
2. To chat or make wisecracks (especially when others are trying to work or have a serious conversation).
This handy Yiddishism derives from a picturesque German source: In German, the verb kiebitzen means "to look on while other people are playing cards" (especially if it's done annoyingly, like standing too close). Even more picturesque, this verb derives from German Kiebitz, the name of a type of little bird that has a reputation for being particularly noisy and inquisitive.
