The combination of sweat from the ballsac and anus that creates a buttery film on the grundle and butthole. occuring usually from an unwashed scrotum creating a smelly odor that worsens in thickness and odor by the minute. Also known as DB or Deeb.
Bobby rubbed his deeb all over his roommates pillows.
I have some killa DB today!
duckbutter is the nasty film of sweat and someother shit that builds up in a man's taint (space between balls and asshole). it got it's term because that shit is thick like butter
i would've stashed the weed under my nuts but i didn't want to get duckbutter on the bag
