7-Eleven is a global convenience store chain known for its bright stores, late opening hours and distinctive door chime, and short clips of that sound have become a handy shorthand online. Creators use the brief chime to set a scene without explanation, signalling snacks, road trips, night shifts and everyday errands in just a few seconds. Because the sound is so short and familiar, it works across memes, vlogs and edits, instantly telling viewers where the joke is taking place.
