Something that is so freaking fly and fresh. If someone's singing sounds like Jesus and Fergy mixed together, their voice is Guac. When you want to describe something as the most amazing, on fleek, dope ass, gucci thing ever just use the word instead of trying to explain how flipping legendary the said thing is. In other words Guac is the new "dope" for you older users.
Person one: "Damn! That is the most delicious, gucci, awesome, beautiful, amazing, exhilarating, dope ass, on fleek steak I have ever tasted! It was a legendary slab of heaven! I had an out of body extra terrestrial experience just from eating it! Wow!"
Person 2: "So you mean it was Guac?"
Person 1: "Guac af man. Guac af."
Person 2: "So you mean it was Guac?"

Another term for weed. This is due to the fact that weed looks a lot like guacamole, especially when you are high.

Cool as hell. This person is a super cool dude. If you have guac you have swag and you are very popular and everyone likes you. Guac can only be possessed by some people, to be bad ass and epic.

(adj.) Derived from Chipotle's extra charge for guacamole. To be "guac" is to be: extra, more than necessary, dramatic, too much, etc.
Camila from Fifth Harmony is so extra.
