Solid, also known as 'hash' or 'rocky,' is cannabis resin (not the green stuff) and isn't so great in comparason, but hey, it's better than nothing.
Apparently, there are some dangers with solid; sometimes it's mixed with camel crap (not so bad) but sometimes it can be mixed with oil to give you cancer that bit more quickly.

Guy 2: "Should we save it for next time or pick up some solid instead?"
Guy 1: "Pick up, pick up!"
Guy 2: "Agreed."
