"Ugly" is its name.

I don't know if that had a name. It's definitely not a mullet. That style pre-dated mullets by 10-15 years.
When guys started growing long hair in the 60s and 70s, mostly they just let it grow with no styling. The style in that picture was one of the first styled hair cuts for guys with long hair. Similar styles were semi-common in the late 70s and early 80s. I never heard a name for it though.
