look up any word, like timebomb:
 
1.
Moments and evenings of drug (alcohol, nicotine, caffeine, et al) consumption for the sake of drug consumption. Usually takes place when people are visiting from out of town or on trips to Los Angeles, California. Especially applicable if you are traveling with the band and hanging out backstage, being treated like you're "somebody" with you're not, and double fisting.
This morning I drank a latte and two beers and smoked five cigarettes all before noon. I was lushing out.

A cigarette and a beer?
Yeah, we're totally lushing out.
