Sıfır kilometre is a common Turkish expression used for vehicles and products with no mileage or use, similar to saying brand new in English. Online, the short spoken version has been shared as a standalone sound clip on soundboards and in short videos, where creators drop it in whenever something looks untouched. Because the phrase is widely understood in Turkish speaking communities and needs no extra context, it works as a quick punchline for unboxings, new purchases and ironic claims about things that are supposed to be new.
