Similar to a dingleberry, but it is a little nastier as it forms on your guch and guch hairs instead of your ass. In addition to toilet paper, turd remnants and ass sweat, it also accumulates guch sweat, and jizz reminents. Multiplied by increased friction and you have a disgusting compilation of grime.
She plucked a guchberry off my guch and ate it like it was a Jr. Mint.
