After a night of heavy drinking, Jane had a bout of diaherra. She flushed the toilet and crashed on the floor. Her roommate Lenora was grossed out to find residuedoo in the toilet.
Doodoo (poop/shit/fecal matter) residue. The brown dark area around the butthole where women usually get bleached. There can be residoodoo on the man's penis after anal sex.
Man homegirls butthole was burnt with that residoodoo. Look like a firecracker went off between her butt cheeks.
