(verb) The act of one individual acting very absurd and maniacal to the point where they no longer think properly and are only focused on laughing and thinking/saying idiotic phrases. However, dankness can be spread easily depending on the intensity of the dankness represented by the individual. Thus, having a whole group of peers dank can be very dangerous.
