A buddy of mine started me on a similar habit that I find obnoxious but impossible to kick.

It started when we were in a meeting with an executive (who was a wonderful man) who -- due to nerves -- used the filler phrase "ya know" about twice a sentence -- like someone who's nervous might use the filler word "um" or "uh."

When the meeting was over, I'd joked that he'd said "ya know" three times in the same sentence and without missing a beat he said "541, I counted"[0]. He went on to explain that when someone repeats a word/phrase, especially if it's a word that's used "to sound intelligent", he can't help but count.

Incidentally, despite having no reason to be suspicious[1], I didn't believe him and being in an IT department with its share of folks with social anxiety and various forms of autism[2], it took all of a day before we were in another meeting with someone who, I think, pronounced "infeasible" as "in-THESE-able." A minor mistake, but he repeated it a solid thirty times and liked to really push that emphasis on the second syllable. We got out of the meeting and I asked for his number. "37"[0] he said. I was one off. It ended up becoming a weird sort of corporate meeting game that we did a few times a month over 17 years. It's a ridiculously easy habit to pick up, it turns out. I've been out of that job for years and I still do it. No real reason, any longer. I don't think less of people who don't have a solid command of public speaking -- as in, I'm not doing it for the purpose of feeling superior or being a d!ck and pointing it out to them. The only people that know I do this (other than readers of my comments on HN) are my kids and the guy who got me hooked.

[0] The exact number escapes me but it was a suspiciously random sounding number

[1] This guy marched to the beat of a different drummer. I have so many stories of outlandish claims he made that turned out to be absolutely true by this point that I should have taken him at his word. By this point he'd shown me a receipt indicating his bill was less than a dime for what must have been two carts worth of groceries (early 2000s), and it was only a dime because he bought something from the register to avoid a negative balance (a problem he's navigated in the past).

[2] Myself and (I suspect) my friend are diagnosed ASD as well.

A sometime co-worker had on display in her office a list of "Molly-isms" (name redacted) assembled by those who worked closely with her. I did not particularly, and don't recall them.

A woman I worked with long ago was trying to tell her boss that something was "a whole new ballgame" but came out with "whole new ballpark." The boss didn't pick up on it, but after work she mentioned it to her husband, and "a whole new ballroom" became a family catchphrase.

I take joy in inventing new broken cliches and save them up for conversations. If I saw someone keeping score I'd ask them to publish a leaderboard so that I could compete for bragging wrongs.

We used to make notes of management-isms and then play buzzword-bingo in company-wide meetings. When you got a full card, to properly win, you were required to ask the management a question that included the word 'house' (saying 'bingo' would have been too obvious, even for our managers).
