Joint – a marijuana cigarette.
Anslinger, Henry – a Federal Bureau of Narcotics Commissioner well known for being vocal about his anti-marijuana views. Also, a really good Sativa.
Nugs/Nuggets – dried buds from cannabis plants.
Up in Smoke – that movie with Cheech & Chong.
Apple Juice – really cold is exceptionally refreshing for a dry mouth.
Roach – the end of the joint, usually pretty small. If you want to smoke it, use a roach clip.
Yay! – What my mind says after I take a bong hit.
