The phrase comes from Güldür Güldür Show, a Turkish television sketch comedy, and is listed as part of its 126th episode in the İdeal Damat sketch. In the scene, the promise to buy a phone is played as a casual, self-interested bargain rather than a straightforward act of generosity, which is why the line works outside its original context. Clipped for soundboards and short-form edits, it has become a handy shorthand for mock promises, negotiations and jokes about phones, gifts and favours.
