'Lady pterodactyl' ?

Wow I never noticed that! I tried to research this and didn't really find anything. There is a group called lady pterodactyl so I thought maybe they were on the soundtrack but no they weren't. I am going to take a guess and say she was calling Olivia that because of what she was doing ie trying to make Viola jealous by "dating" Duke and thus since Viola liked Duke she was mad and calling her names. Sorry for long winded post.

Amanda Bynes was just ad libbing that part. Not sure what her inspiration was.
