Hi! A few questions

Hi there. I just finished watching season 7 of RPDR, and I had a few questions. First, I would like to say that I loved the show and learned some new things about drag. Before I watched this, I thought drag queens were just teenagers who dressed like women on Instagram, or just smearing makeup on their face over their neckbeard like on r/Drag. I didn't know about the performance part of drag. However, there are a few things about the show I don't understand.

1. Are all drag queens bottoms? I ask because all the contestants on the season I watched said they're bottoms, but I'm not sure if being a drag queen is exclusive to bottoms.

2. Why are the contestants referred to like people, even when they're black?

3. Here is a list of things said on the show that I do not know what they mean. I would love it someone could explain them to me.

    * Okurr/Oquanch
    * Shemale. I always found it funny when the queens said this, because the whole idea of the show is based on misogyny.
     * Fuck. Ru always says this at the end of an episode. I have an idea of what it may mean, but I'd like to be sure.
      * Shananay you stay/ chasse away
   

Thank you.
