There is a series of expressions in English starting with "just for" that mean "for no particular reason." Examples include:
Just for the sake of doing it
Just for the hell of it
Just for shits and giggles
Just for laughs
Just for fun
Just for kicks
One of these expressions is:
Just for a kick in the pants
In this context, "a kick in the pants" means "fun".
Normally, "a kick in the teeth" as an idiom means something like "a sudden and devastating event" or "a painful setback". However, in this context, it takes on the meaning of the primary expression, and the primary meaning is still "for no particular reason."
The secondary implication is that the behavior is known to be unproductive or disappointing--that he's not checking for any particular reason, but he keeps doing it, even though he know he's going to be disappointed every time he checks.
So the sentence might be rephrased something like:
I monitor this frequency every other day or so. I don't have any good reason to, and I know I'm never going to hear anything, but I do it anyway.
Feminists place this blanket judgement over all men
in other words, all men are thought of in the same way, covered like a blanket, even though they are not all the same. Another idiom for this is
painted with the same brush
tarred with the same brush

It is more common to say the pendulum is swinging (or has swung).
To say this means that thought, practice or political leanings (for instance) have shifted in one direction, but it is expected that at some future time they will swing back —because they have in the past.
An example is educational theory with regard to phonics. For some years, schools will try to teach spelling without teaching phonics, but they inevitably revert to teaching phonics.
As these swings can take years, the metaphor assumes the decay of the amplitude of swing to be negligible.
