The act of taking a rip of a bowl, hitting a hookah until your lungs are completely full of smoke, and then holding it in as long as possible. This is more of an act of showmanship than anything, because no extensive research has been done to see if it enhances the high and/or causes you to get high faster. This is most likely the case though, as holding it in longer allows your lungs to completely absorb all applicable substances. While experimenting with the process I noticed that while high one is able to hold one's breath significantly longer than while sober. This is what makes the Overload potentially dangerous as an individual will not be able to comprehend the extreme amount of time they have been holding their breath and black out. Therefore, it is advised that one does not partake in this activity alone. Hypothetically speaking, the Overload could be done with a bong or a joint, but it has never been attempted.
After ripping the bowl, Edmund surprised everyone by picking up the hose and attempting the infamous "Overload."
