42nd Street in New York City (the southernmost part of Times Square). Back in the day, a center of total depravity, especially between 8th and 9th Avenue, but currently Disneyfied.
When your taking a shit and your initial push produces a very long gnarly turd that doesn't break off from your ass and hangs there like an icicle. Typically this turd is touching the water.
Mark: Did you hear about Brian's deucecicle?
Adam: Yeah, rumor has it that was roughly 11 inches.
Mark: Yeah, he said he squirmed on the toilet vicously until the deucecicle broke off his asshole.
Adam: WICKED BRO! WICKED!
