Obviously Goku is not insult-heavy, although he does trash-talk during a fight when he feels he's on top.
In my opinion, along with humilliating him in combat, this was the most insulting thing Goku ever said and did. He disregards Freeza completely after making him tremble in fear. I also think that it's subtle, but when Freeza attacks him again and Goku calls his attacks desperate and pathetic and tells him to learn some moves, he's alluding to the fact that Freeza never had to put in any effort since no one could oppose him. He's no martial arts expert and can't even sense ki. He rarely even fought. Things that Goku exploited while being infinitely weaker. Now that someone was in the same realm as him strenght-wise, he was easily outclassed, toyed with. I've never seen Goku being so condescending before. Even against Moro he was sort-of offering advice. Here he completely berates Freeza, shaking the very foundation of his standing. Not even the prospect of fighting someone as strong as him again made him excited. He was driven by hate here.
