To get down means to participate in something with other people. It could be anything, really, but it generally is associated with smoking some ganja.
Yo, you wanna get down on this blunt?
A legal intoxicant. Alcohol is more or less yeast's piss, yet some people drink it like water. I really don't see why it deserves to be legal. If the gov't weren't making money from it then it certainly wouldn't be. Alcohol kills more people than all of the other illegal drugs combined, and that's not even including its indirect deaths. Many people, if not everyone, seem to think alcohol is harmless simply because it's legal and many people do it. It causes a considerable amount of damage to the brain and liver. Despite this, people who consume alcohol have told me marijuana will kill my brain cells. I always get a kick out of that.
Person A: LET'S GET WASTEDDD!!!!!!!!!!
Person B: No thank you, I'd much rather enjoy a blunt to the dome.
Person A: Fuckin pothead! You're frying your brain you know!!!!!!!!!
Person B: You do know alcohol has been proven to cause both brain and liver damage right? And that there is no conclusive evidence that marijuana harms the brain?
Person A: You stupid druggie....Um...You don't know what you're talking about!
Person B: Yeah, whatever. Have fun with your booze buddy. *Proceeds to light L*
