ELI5:Butler's Gender Performativity

I am trying to fully understand Judith Butler's theory of gender performativity and I would like some help.
gpt
The basic (and simplified) idea is that gender--what we think of as masculine and/or feminine--is performed in the ways we act, speak, dress, move, etc. and doesn't really exist outside of that performance. We learn how to perform this way from dominant culture and conventions--what someone might  (incorrectly) call "normal male" or "normal female" behavior. But these "normal" qualities (and genders themselves) don't actually exist--rather, we are all repeatedly mimicking them and are rewarded for doing so (or punished for not doing so). We merely impersonate the qualities we've been taught match the gender we've been told we possess (like females being demure or males being aggressive) until those impersonations (and gender itself) become belief and seen as something natural and assumed. 

She so talks about drag and subversive gender performance, but that gets a bit more complicated. Is there a specific point you're stuck on?
