A predominantly black neighborhood in West Philadelphia that borders predominantly white and Jewish. Bala Cynwyd in Lower Merion via city line. Black people from Wynnefield like to cross city line and steal the white kids bikes on their lawns.
"Dude, my friend from bala cynwyd got his bike stolen, returned, and stolen again in one week!!"
