Duj ngaDHa' ("person who is wildly irresponsible, out of control, undisciplined")

This expression means literally "unstable vessel, unbalanced vessel." Duj is "vessel"; the verb ngaD ("be stable, balanced," here followed by the negative suffix -Ha') normally applies to a ship or a physical object, not to a situation or a person. It would be inappropriate to refer to a person as ngaD or ngaDHa' in a phrase such as tera'ngan ngaDHa' ("unstable Terran"). A standard verb that is close in meaning is ngIj ("rowdy, unruly"), as in tera'ngan ngIj ("rowdy Terran").
