It seems like Boston Bruins head coach Jim Montgomery was livid with the officiating during Game 3 of the second-round Stanley Cup playoff series against the Florida Panthers, and that frustration carried over into Game 4. Montgomery was visibly upset with the NHL officials during Game 4, especially after a game-tying goal from the Florida Panthers was allowed to stand despite controversy.
The Bruins and Montgomery believed the goal should have been disallowed because Panthers forward Sam Bennett pushed Bruins forward Charlie Coyle into Bruins goaltender Jeremy Swayman. Although there was no audio of Montgomery's interaction with the officials, his body language showed his extreme frustration with the referees.
While I'm no expert lip reader, it appeared that Montgomery may have been swearing at the officials in French, which would make sense considering the referees for the game were Frederick L'Ecuyer and Francis Charron. If my interpretation is accurate, Montgomery may have said "Mange de la marde," which translates to "Eat s***" in French.
