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.
