[Opinions] since you asked politely ..
Drag Race refers to Ru-Paul's Drag Race, which is kind of a beauty/talent competition for drag queens/transvestites. American TV show. Nothing racial about it. The show is pretty popular; I think Congresswoman Nancy Pelosi was recently a judge on the show.
I only ever watched a couple episodes when it first started, quite a few years ago, so I don't know if it's changed much, but as I recall the performers were very over the top and glam in their clothing and makeup and mannerisms, many being outright stereotypical. I have no idea how many, if any, hwere called Kimmie but Kimmie just feels like a stereotypical drag queen stage name. Maybe there's a famous one in the past using that name and somehow it has seeped into my perception of the name, I don't know.
