The annoying smeary, putty-like base that when defecated, causes the "skid marks" in ones underwear if not properly cleaned. Resembles fudge but can be a number of colors and textures. Great for "sandwich based" practical jokes.
"I forgot to wipe man, now I got skidmarks from where that smudglet streaked by!"
