Antojos are uncontrollable or sudden cravings and desires to eat specific foods. They are often strong inclinations or whims that arise unexpectedly. In a cultural context, especially in Mexico, the term "antojo" can also refer to snacks or small treats called "antojitos." People use this word to express a desire to eat something tasty that is not necessarily driven by hunger but by a momentary craving or whim.
The word "antojo" can also have other meanings such as birthmark or beauty spot, but its primary and most common use relates to cravings for food.
