Get the lang mug.
The residual weed left over from an already vaporized bowl.

In order to produce this obviously a vaporizer must be used. After getting a vaporizer pack a full bowl of weed. Vaporize and Enjoy. After vaping, the leftover weed typically comes out a brownish to black color, but occasionally it's also slightly green. Some claim that there is still THC and resin left in this byproduct, which produces a mild high when smoked from a bong or pipe.

Lang can also sometimes be used in spliff in lieu of tobacco.
"Hey man you want to smoke this lang?"
"Brian there no THC left in the lang"
"I swear you still get a high from it"

Get the Lang mug.
A new versatile style and usage of the english language. The process mainly consists of taking the first syllable of a word and using that in place of the original word. Sometimes a slight change in the spelling will be done to make the word more discernible from other words. One of the very first words used in this language was nuth.
Hey Joe, what lang are you speaking?
Mike thinks there is nuth wrong with speaking a new lang.
I was sick and ti of having nuth to do until I learned this new lang.
