I think he's thinking of the English verb shadow, meaning to follow someone secretly. You can't use QIb for this.
Say something like tlha'a tlha'; pegh He follows Klaa; he is secret or tlha'a tlha'; So''eghpu' He follows Klaa; he has hidden himself. Klingon is very willing to let you shove two sentence together to form what in English is a single concept.
An idiomatic way of saying something quite similar to this is:
cha'maH cha' joQDu'
It means that something is not right. If a situation is suspicious, you say there are twenty-two ribs around here. If a person is suspicious, you say that person has twenty-two ribs.
Klingons normally have twenty-three ribs. If, for some reason, a Klingon literally has only twenty-two, one would say of that wa' joQ Hutlh He lacks one rib or something similar.
So Max_Matthews can say naDev cha'maH cha' joQDu' tu'lu' There are twenty-two ribs here to mean There's something not quite right going on here, which is pretty much how I interpret his use of very shady.
