pocket munching is an activity typically performed in a place where alcohol is served but no food is available. Thinking ahead, the pocket muncher will randomly pull food out of their pocket and start munching. This is done in order to achieve optimal alcohol metabolization, ensuring that more alcohol can be consumed without the unwanted conditions that lead to memory loss & hangovers. Pocket munching is a popular and considerate gesture among experienced alcohol consumers.
