schusslich
This is interesting, Rapunzel. In my PA Dutch family, schuschlig (pronounced shushlee, 'u' pronounced as in 'put') means 'careless', 'sloppy', or 'lazy'. If one of us did a poor job on a chore (gave it a lick and a promise), my mother would say, "Don't be so schuschlig." The word for antsy, or squirming, was rütchig, pronounced with the u-umlaut sound midway between 'rutchie' and 'richie'. There is also a noun rütchig denoting a smoothed area, such as one on ice or snow, for kids to slide on, like you read about Bob Cratchit using in Camden Town on his way home from the office on Christmas Eve. The verb is rutschen, as in, "Don't rutsch about so!"
