chack

To toss up the head frequently, as a horse to avoid the restraint of the bridle.

(ice-skating) To not broadcast a medal-winning or otherwise memorable or crucial figure skating performance. This only occurs in a live broadcast because the network has to decide which programs to show and which to cut in the interest of time. If a skater is low in the rankings and several big names are set to skate later, that performance may be cut.

Of birds: to make a sudden harsh call.

A snack or light hasty meal.
