caption_attribution_description: English: A polyester (“plastic”) house ball, having large, loose-fitting, non-custom finger and thumb holes in a ‘’conventional grip’’ (fingers insert to the second knuckle, so the thumb hole is relatively close to the finger holes).
context_page_description: 180: A pinsetter malfunction in which the sweep bar is stuck at the back of the lane, halfway through a pinsetter cycle.
  270: A pinsetter malfunction in which the pin sweep is stuck at the front of the pin deck and the setter is unable to lower the next set of pins. In some bowling establishments, this malfunction is incorrectly referred to as 180.
context_section_description: Carry: See pin carry.
  Carry-down: Process by which balls, having picked up oil from the oil pattern, deposit it in the normally-dry back end to cause subsequently-rolled balls to "slide" and thus extend their length before hooking. Carry-down is one aspect of lane transition. Distinguish: breakdown.
  Challenge match: In Japan, an event where a popular bowler, usually a licensed professional, hosts a tournament, allowing paying participants to compete for money and prizes. Typical event consists of three games. The host receives a payment, minus the funds used to pay off the bowlers who defeated the host.
  Cherry pick: See chop.
  Chicken sandwich: Three consecutive spares, preceded and followed by strikes.
  Channel: Formal term for gutter. One of two trough-shaped structures surrounding a lane to catch errant rolls.
  Cheesy cakes: Also: "cake shot". Lanes on which strikes are relatively easy.
  Clean game: A game with a mark (spare or strike) in all ten frames.
  Chop: In an attempt to convert a spare having (at least) two pins, to knock down a near pin while failing to knock down a pin that is immediately diagonally adjacent. Example: knocking the 2 and 4 down but leaving the 5 pin. A modern interpretation of the term denotes picking only the middle pin out of, for example, the 1-3-6 or 3-6-10 (right handed release).
  Closed (body position): Describes a body position in which the shoulders (especially) are directed squarely downlane and not to the outside; is commonly adopted by strokers, a style favoring repeatable accuracy over power. Compare: open (body position).
  Clover: Four strikes in a row. A reference to four-leaf clover.
  Cock and balls: A 1–5–8–9 leave.
  Come back: Of a ball: to hook. The term is usually applied when a ball seemingly was headed too low but ended up hooking adequately.
  Conditioner: Lubricating lane oil.
  Conventional grip or conventional fit: A ball grip in which fingers are inserted to the second knuckle from the fingertips; characteristic of house balls. Compare: fingertip grip.
  Conversion (convert): In the second ball roll of a frame, the knocking down of all pins that remained standing after the first roll, so as to achieve a spare for that frame. Term is often preceded by the number(s) of the pins involved (example: "3–6–10 conversion").
  Core: A dense structure inside a ball that can be shaped, located and oriented to strategically affect ball motion. Sometimes called a "weight block". See Bowling ball#Effect of coverstock, core and layout on ball motion
  Count: See pin count.
  Coverstock: The material comprising a ball's outer surface (cover), which determines the ball's frictional engagement with the lane and thus substantially affects ball motion. Coverstocks include polyester ("plastic"), polyurethane ("urethane") and reactive resin ("reactive").
  Cranker: A bowler who rolls the ball with high revolutions, a style favoring power over control and repeatability. Compare: stroker.
  Cross over: Of a ball: to pass from the right side to the left side of the center board (for right hand deliveries) before impacting any pins. See Brooklyn.
caption: Conventional grip finger holes are relatively close to the thumb hole (compared to balls with fingertip grip).
