When you leave on a perm(hair straightener, ie...soft sheen)too long. And your hair becomes very straight and thin, like the fake silky doll hair of a cabbage patch doll.
HOT like the perm on the back of your neck
Left it in too long
Now ya got Cabbage Patch silky(Thanks to Big Boi of Outkast re: Morris Brown)
It means like a dog in heat, a guy can smell that the female is in heat. He has the hots for you!
All that nasty stuff girl does for him, got his "nose wide open"
