headcrack
n.— «He says the game pads his income substantially—he said he won $1,000 playing cee-lo in July alone. […] The best rolls are called “headcracks,” the highest of which is a “cee-lo”: a roll of a four, a five and a six. Other good rolls are three of a kind, known as triples or “trips,” or a pair of any number plus a six.» —“Rolling the Dice on a Warm Night” by Sarah Maslin Nir New York Times Aug. 16, 2009.
