There’s quite a few you’d find with a search, phrases in general, however one example out of many is the simple phrase: cakewalk, or ‘taking the cake’. The phrase has origins as a sort of dance African slaves would perform in order to win a prize of a cake.

Here’s a source I found on it, which is short, however there is a longer Wikipedia entry about too: https://birminghamhistoricalsociety.com/2023/02/06/history-of-the-cake-walk/

Edit: I’m sorry I remembered this is about sexual stereotypes. I’m way too high since I went down a rabbit hole and can’t decide on a source. Sorry lmao.
