A pet peeve of mine is the "partner" who gives the foul-tip signal (baseball) when a defender swipes at the ball attempting to block the shot when I can clearly see contact on the shooter; it is even more infuriating when the call is IN MY PRIMARY.
Additional Pet peeve: (2 for the price of 1

) The "partner" (as a Lead) who "Toilet swishes" an airballed FT.
