bothin'
To be in such a state as to smoke marijuana and drink alcohol simultaneously. Invented by Georgian indie boys in the mid-2000s, the term quickly spread to Tennessee as a white kid's version of "crunk". Avoided by frat boys, "bothin'" is used almost exclusively by the musically and poetically inclined. Not to be confused with the emo boy variation, "catatonically depressed".
When we arrived at the soiree, John was passed out on the sofa with a bottle in one hand and a joint in the other. Clearly he had been bothin'.
