Rules Analysis
The disc is dead, and no turnover is possible:
After the pull or after a turnover when the disc must be carried to the location of the correct pivot point, until a pivot is established; or
After a call which stops the play or any other stoppage, until the disc is checked in.
What:
A player signals a foul or violation and yells "stop" or uses the incorrect name for a call. Result: The call should be dealt with as if the player has used the correct call.
Why:
It is clear that the player has seen a breach of the rules. This takes precedence over the technicality of knowing the correct term.
Extra:
The player who used the wrong term should make it a point to learn the correct term (Rule 1.3.1) and more experienced players should tell them the correct call (Rule 1.8).
