Get the Rum and bummug. What your dog leaves on the patio. Normally firm, well formed stools that bear an uncanny resemblance to walnuts, or pieces of chopped sausage.

Get the Bum Nutsmug. A filthy man who thinks his idiocy attracts women. Usually fat women will tolerate his stupor, and are willing to sleep with him.
"Haha, look at that krum bum hitting on Shamoo!"
"I heard krum bum tried to stick his penis in some 400lbs chick's belly button thinking it was her vagina!!!"
