A realm of darkness and depression between hell and the earth's surface where innocent males are sent to by attractive/nice females when acting friendly as an attempt to build a good relationship with a female to interest them in a boyfriend and girlfriend relationship. This horrible place is to be avoided at all costs and all males are advised not to develop a crush on their close female friends in order to avoid this.
