Hairgina 

When a lady lets her pubic hair grow to such an amount that her vagina is no longer visible.

I better get laid tonight because of all the effort I put into removing my hairgina.

I couldn't go down on her because she had a full on hairgina.

hairgina 

A parting of hair in back of ones head that reveals a balding area.

I usually tease the hair in the back of my head to conceal my hairgina.

Hairgin 

When one person girl/boy has never cut, colored, perm, or dye, etc. there hair!

See virgin or lipgin << same as those but it describe hair

I was once a hairgin until I was 6 years old I lost it to my first time having a perm coming into my hair and last month I got in color!

I don't regret my first time and I don't wish for it back I love it!!!!
