What does Serena Williams' crip walk mean in the specific context of the superbowl?

Most threads I search about crip walk in general is just people dancing for fun, but then there's all these reactions about how big of a deal it was for Serena Williams to crip walk to a Drake diss track. Are crip walks insults? do they have other meanings? Can someone explain it to me like I'm some 5 year old neurodivergent child who doesn't understand social trends?
