Pronounced, "Choo-low." A penis that's wider than it is long, but isn't very wide or long. Something like a tuna can from a doll house, or a scale model of a choade.
After years of painful operations to correct his inverted penis, the young man was happy to be left with even a non-functioning ciullo.
