What does it mean to supercharge a drink?

Supercharging a drink typically refers to enhancing it with additional alcohol, specifically an extra shot of liquor. This concept is commonly used in bars and restaurants to provide customers with a stronger beverage for a more intense flavor and potentially greater effects. It's a popular option for patrons looking for a more robust experience from their drinks, especially in settings like Dave and Busters, where social and celebratory drinking often takes place.

The other options do not adequately capture the essence of supercharging a drink. Adding extra ice can affect the drink's temperature and dilution, mixing with energy drinks may create a specific type of beverage but doesn't inherently imply an increase in alcohol content, and serving in a larger glass simply changes the container without altering the drink's strength. Therefore, the most fitting interpretation of supercharging a drink is adding an extra shot of liquor.
