Popularized by the rap group ExMortis, a snackpack is when a woman (usually someone's mother) performs analingus on the rectum of the man while he defecates.
"My ass become a vortex and began to spit faster;
yo mama's face became a national disaster area.
Makin' her face a little scarier,
and my colon drips all night, so you'd better beware"

"I ripped off my drawers, and spread my asscrack, and I made that nasty bitch make herself a snackpack"
