What does "Ounce" mean?
Definition: An ounce is roughly equivalent to 28 grams, and is the most common denomination of marijuana when purchasing or buying in extremely large quantities. In actuality an ounce is a sizable amount of weed, and most people would never desire for anything more than one ounce at a time. An ounce of marijuana will usually fill a typical zip-lock baggie or mason jar (which is why the slang term "zip" can also refer to an ounce of pot).
Example usage for Ounce
"I'm gonna pick up an ounce later tonight, that'll last us a couple of weekends."
