2.
A woman who walks the streets peddling herself for sex; a prostitute.
After Jim-Dandy kicked Buffy's ass out of the crib, she turned into a righteous curb crawler, peddling her skinny white ass on the street to get a fin for another rock of crack. She wound up sleeping in a Port-a-Potty downtown until some anonymous john slit her thoat.
