weq doesn't mean hit an object which just happens to be a percussion instrument, whether or not the hitting is intended to make music. If a car were to ram into a drum, that would not be weq, but it certainly would be a kind of hit.
If you're rhythmically slapping your knees, or even just once when timed for audible effect, that's weq. If you just happen to hit your knees once at random, that's not weq.
I agree with you totally on what type of action constitutes {weq}. But you're correcting me for something I didn't say. I just pointed out the assumptions implicit in your reasoning, namely (1) the disambiguator limits the object of {weq} to instruments, and (2) Klingons consider the knees to be instruments when used in a like manner to drums. These strike me as the sort of literal thinking that is so useful in computer science, and the second purports to know what Klingons would think. jaS jIQub.

There's no evidence in Star Trek of Klingon lawns. Even among humans, it's something of a local fad. Klingons would probably find lawn-keeping to be bizarre behavior. In that case, they might well speak metaphorically (and mockingly) of giving the grass field a haircut.

You're playing the "a Klingon would" game again.
