Where was the inspiration from when Ellie curses after she kills her enemies in TLOU?

I’m trying so hard to find the video where they were talking about the gameplay of TLOU2 and how Ellie curses after killing enemies she comes across, Naughty Dog got inspiration from a game to bring it into the game. Would be much appreciated for your guys help on this if anyone knows.

It’s just this small thing that’s bugging me that I really want to find out lol.
