A spitting blunt is when a marijuana cigar (blunt) is "spitting" out marijuana when you inhale on it. It is common curtosy to let the person you are passing the blunt to know it is "spitting". This can sometimes be difficult if your own your last hit and it "spits" on you. In this case, you coughingly say "its spittin".
The act of one randomly jizzing in their pants. It doesn't matter if this person is alone, sees a lady with great ideas, or in a circle of men (if your into that).
