Team Fortress 2 is Valve's class based multiplayer shooter first released in 2007, and the Scout is its fastest class, known for cocky voice lines during combat. Femscout is a fan made female take on that character who became familiar through community artwork, mods and videos. Her version of Let's waste 'em keeps the Scout's battle ready attitude in a higher pitched delivery. The line stays popular in gaming edits because it is short, clear and instantly signals an incoming attack without needing any setup or context.
