The sound is tied to Team Fortress 2, the Valve team shooter whose Scout is known for cocky, fast-talking attitude. Femscout is the fan-created female version of that character, widely used in fan animations, edits and memes rather than as an official in-game character. The short look at me line fits that confident persona, which is why it has been picked up for soundboards and short-form edits where a character demands the spotlight.
