These are only best guesses by the context in which they are used. So far, as I can tell:
wikket - outsider (non-hozen humanoid)
slickie - fish
grook - also grookin' - killing or ganking
dooker - feces or butt
ook - smash or crush
shiny - an item with visual appeal
Also, would like your input for your interpretations of what they say.
