The Montreal Canadiens defenseman made that abundantly clear in the postgame scrum, according to Sportsnet's Eric Engels:
Subban's second goal of the season - and first in 34 games - tied the contest in the second period before the Penguins scored a pair en route to the victory.
"I was just frustrated," Subban said following his tirade, according to Engels. "It's normal after a game like that."
The blue-liner, who registered four shots on goal and logged 30:01 in ice time, was named the game's third star.
Subban now has 29 points in 43 games, and his 27 assists rank sixth in the NHL and third among defensemen.
