Having an extremely intense bowel movement that requires a long duration of pushing and squeezing while "ghost-pedaling" an imaginary gold spinning loom while hunched over.
Dude, I ate sushi for lunch and mexicanfor dinner, I gotta stop home and bust a crumplestiltskin.
Cumpelstilskin is a dwarfish creature that appears to satify the needs of the whores throughout the community. He resembles our favorite childhood fairy tale creature Rumpelstiltskin, however instead of spinning straw into gold, he spins fecal matter into cum. The gift of spinning fecal matter into cum is seen as a metaphor for the value of fecal matter, and the need for cum.
