A seemingly hard and painful shit that can't seem to come out due it's size and hardness. A barbed shit often feels very sharp as if it's got splinters stuck in it.
Similar to a sharp shooter
apart from the fact that a barbed shit comes out very slow, and a sharp shooter splutters out fast (but still painful)
I just couldn't squeeze out that last chunk of barbed shit. It felt like my crack was on fire.
