If you are asking about "Desi's big zip" in a social or cultural context, it most likely refers to a "large ounce" of high-quality or potent cannabis associated with a person named Desi, or a "Desi" (South Asian) source.

While the term "zip" is generally used for a standard ounce, a "big zip" might colloquially imply: A generous measurement (slightly over an ounce).

In cannabis slang, a "zip" is a common term for one ounce (approximately 28 grams) of marijuana. The name originated because an ounce of dried flower typically fills a large Ziploc bag. Contextual Interpretation
