in-game signals between officials

[Back In The Saddle]

'Round these parts it's common for partners to use index+pinkie or thumb+pinkie to indicate an upcoming bonus situation, an extended fist to indicate an upcoming media timeout, the "sliding index finger" to indicate that the upcoming throw-in is not a spot throw-in (usually exchanged at the beginning of a time out), index finger extended upward to indicate we're under 1:00 remaining in the period (quite often this is withheld until we're at about 30 seconds), tapping the chest to indicate either "I've got clock" or, more rarely, "I'm the new lead" (used to sort out confusion over a missed rotation). The only other one that comes to mind is the "two fist twist" used to communicate the need to tighten up the play calling.
