"Put dispenser here" comes from Team Fortress 2, Valve's class-based multiplayer shooter released in 2007. The line is associated with the Engineer and became familiar through voice command spam, machinima clips and TF2 meme culture online. It stayed popular because even people who barely played the game recognize the phrase as shorthand for wanting supplies, healing or support in one exact place. The sound still shows up in gaming compilations, parody edits and nostalgic posts built around classic TF2 voice lines.
