I made several vulgar euphemisms for that first pumping that I shouldn't type in this comment.For me it's that we get these endless scenes of the kids pumping their fists and doing harm to our heroes with no one doing anything about it, so it's the frustration. Like I'm sure there are times when Kirk or someone could have run up to the kids and beat the crap out of them to stop them, but no one wants to see an adult beat up a kid on tv, so the kids were allowed to just stand there fist-pumping away.
