When you are smoking the last bit of pot in a pipe, and one of the hot ashes shoots through the bowl and hits the back of your throat. Can usually be seen as a bright orange ball flying through the length of the pipe if it is made of glass.

When some little bitchboy is acting like a little tiny pee pee poo poo baby and messing up the group plans.

its when you are getting your pot out of it's medium of transportation, and the shake flys all over the place..
