I’ll just add at this point I have seen many admissions officers address this in some way, and they pretty much all say something very similar. It isn’t necessarily an ethical violation to use business-speak in these contexts (although it could be), but it is a terrible advocacy strategy! The applications they love are the ones that stand out from the sea of such applications using business-speak. So at a minimum, you should avoid doing that.
That said, there is a real art to writing interesting activity descriptions. It is NOT about making them sound more formal/“impressive” (in the way ambitious but rather inexperienced HS students tend to think of things being “impressive”). It is about packing strong, specific images into the description that the reviewer will actually find interesting, ideally amusing, because that then reflects well on the personality of the applicant.
OK, so this is purely a hypothetical, but suppose your activity involved late evening discussions. So, suppose you could write something like this:
ACTIVITY NAME (served as “pizza king” and made sure we had carb fuel for late-evening bull sessions)
You may think that sounds less than “impressive”, but I think there is a very good chance an admissions officer would actually find that refreshing and charming.
And my final point is their ultimate goal in holistic review is to find applicants the other students in their community will love to be around, as roommates, classmates, in activities, and so on. And you know what college students do a lot? Have late-night bull sessions. And you know who is always popular? The person who happily will go on a pizza run for the group.
So if you are doing this right, you are painting a very specific picture of the various ways in which you will be a valued member of your college community. And that is the actual goal here.
But if you instead wrote:
ACTIVITY NAME (catered to the needs of other members during collaborative meetings)
You will have failed to say something specific and interesting, and lost an opportunity to actually stand out as someone who would truly be valued by other students.
