I speak Arabic and the saying you’re looking for is أنا احب أبوس الحمير which roughly translates to "I love eating candy“ although it’s not directly possible to translate as Arabic is a very metaphorical language.

The reason why the man was emphasizing his love for candy is, simply put, biological. Through evolution, our brains developed strong reward pathways—primarily involving dopamine release—in response to sugar, as it was a high-energy, survival-critical food source for our ancestors, making its consumption biologically pleasurable and motivating.
