I would seriously pay, even a subscription fee, to have that ability downloaded into my brain. The first few mentions of "like" don't typically get me, but the more it's used the irritation level grows exponentially...
Strongly suspect it's age-related. I noticed the comment you responded to stated 'along with lower key words like "right" or "uh uh"'.
The turn of phrase "low-key" became popular in the 2010s - I barely, if ever, heard it used before then - so my guess is that this user is in their twenties to early thirties.
