look up any word, like kappa:
 
1.
The man with a plan, and that plan is to get crunk. A carnacious individual is the life of the party. If you see a lot of swagger, say carnacious.
Never stopping, always raging, that's carnacious.

2.
a quality of being carnageously tenacious. Persisting in carnage and other riotous and ridiculous acts, even in the face of potential obstacles such as trouble with the authorities, physical trauma, and/or death.
Dude, if we weren't so carnacious at that party and started a riot, that mondo DJ wouldn't have played that extra set!
