Why chicken jockey?

So as we all know the movie has a ballistic reaction in the theatre every time Steve says something from the trailers

But the chicken jockey line always has the biggest reaction (I can confirm this as I work in a cinema and saw the reaction to each meme over 4 times by now)

In my country the movie premiered on April 3rd before the trend went online and even when I saw it on that day chicken jockey had the biggest reaction

So I ask what makes that line more “explosive” than any other line from the trailers like “I am Steve” or “flint and steel”?
