The part of your nose that seperates your nostrils. It can be
pierced for a "
bull ring" type effect. Also if you do a lot of cocaine over a long period of time (like daily use for years) you will likely
rot a hole through your septum, sometimes destroy it altogether and get left with one big nostril...nasty.
Notable people with pierced septums include
Keith Flint (from Prodigy) and
Saint Dog (of Kottonmouth Kings fame)
Don't do cocaine daily for a long period of time, you can do some
serious damage to your septum.
Do you think it is possible for a cocaine user with a hole erroded through their septum to wear a ring through it?
