its very sweet, when i was growing up in port Harcourt, one woman used to hawk it every morning, its called Epiti

very correct bro, i noticed it first wen i wanted to clean my nose with a handkerchief, u need to seee the black stains on the handkerchief, i was surprised, every morning wen i want to wash car i see a lot of black stuffs on the car then i will be wondering how it came about.... the black feet also is true, sometimes i just enter the bathroom to scrub my feet, after some minutes it will stain again, right now my sister doesn't walk around on barefoot

meanwhile Amechi has this to say
