Untrimmed female pubic hair, usually rather long and widespread, often as far as the legs and stomach. Refers to the trend in the 70s of women not shaving or trimming their body hair.
Women with 70's bush should not be walking around in daisy dukes or miniskirts.

wild, overgrown, ungroomed pubic hair
I ain't going down on her anymore without a Dustbuster. Last time I did, I was hocking up hairballs for a week, cuz she's got 70's bush.
