Bumslaw
The accumulation of residue, in one's ass-crack, that appears after long periods of bodily neglect (read: poor hygeine). The residue is composed of various elements; the most common are: poop, ass pubes, accumulated sweat resin (aka: salt cream), hemroidal or vaginal medication residue, blood, lubricant, and fuzz from undergarments.
I went camping last week and didn't shower for 4 days. I had to scoop the Bumslaw from my crack with fpoon!
Get the Bumslaw mug.
