Kalabak is a natural spring water name strongly linked to Eskisehir, and its delivery calls are part of everyday street life for many residents. Clips built around the shout spread through Turkish social media and soundboards because the phrase is short, local and instantly repeatable. Outsiders may not know the reference, but the rhythm makes it easy to reuse as a joke announcement. It remains popular as a niche regional meme, shared by people from Eskisehir and by creators who enjoy turning ordinary public calls into comedy.
