Rory McIlroy was in no mood for hecklers Saturday at the Ryder Cup ... especially when someone in the peanut gallery yelled, "suck a d***."
You really have to listen closely to the video ... someone screams "SUCK!!!" which is then followed by a guy with a low voice, commanding, "Suck a d***."
The guy in the striped shirt seems to be the offender, and he was yanked from the crowd by security and removed.
It wasn't that Rory was doing badly ... quite the opposite. But there's an unusual amount of testosterone at this tourney ... and Rory drew a line in the sand.
