Actually the "Let's Go Brandon" phrase has an interesting origin of a reporter trying to say the crowd was cheering for a Nascar driver named Brandon while they were clearly chanting "Fuck Joe Biden". So it became a euphemism for the actual phrase they were cheering and a callback towards that event that shows the media's biased coverage.

So yes, I think that phrase is a bit deeper than saying someone has tiny hands? over and over for a decade.
