> Like the cockroach of Ngerdobotar, staying on till it became white.
Presumably if a cockroach remains in the darkness for a long time, as one at Ngerdobotar (in Aimeliik) apparently did, it will turn white. Application pertains to a visitor who stays on and on, especially one who is not helpful in the household. Such behavior is not properly human; the person is somehow different, like a white cockroach.
> It's like the first drop of feces of Ngiraidechiil.
i.e. the best or worst is yet to come. Ngiraidechiil had just assembled his fishing gear when he felt the urge to relieve himself. In the bush he started to do so when, with the first small drop of feces, a rat scooted under him and made off with it. He looked at the scurrying animal and called: "Wait, you, that was just the first drop, more and bigger ones will follow!" The resulting saying has to do with desirability of delayed rewards. It was used, for example, with reference to the first rations received from the military following World War II.
> Like the gods of Ngebukd, completed up above.
As part of the festivities of a village feast or in celebration of some event, such as the completion of a community hall, Palauan young people produce a variety of named dances. One type of dance, called ruk, was never conducted in Ngebukd (in Ngaraard, northern Palau). It was said that the gods of the village had done their dancing in heaven before coming to earth and thus it was not necessary for the people of Ngebukd to dance. The saying pertains to a completed task, indicating to another that the work need not be repeated.
> You're like a beetle that burns itself by flying into the fire.
You're always getting yourself into trouble.
> It's like the rat of Ngerard, which eats up all your coconuts and (then) all of ours.
It's a decision, plan etc. that will backfire. A pet rat owned by Mad, chief of Ngaraard, ate the coconuts of most of the chief's neighbors, then, still hungry, ate the chief's own coconuts.
