The hair between your spank bag and o-ring. If you're not shampooing that shit regularly, then it'll turn into.... Dirty Gooch Hair!

Dirty Gooch Hair can sometimes get dingleberries caught in it. Always try to soap it down with the families bar of soap so it don't stink like a black street urchin. Bitches don't like dirty gooch hair so try shavin that shit off or maybe perming it.
