Griffiths played for Hibernian on loan from Wolverhampton Wanderers between 2011 and 2013, and the 26-year-old Scotland global striker appears to have made fun of Rangers on Twitter after their defeat to Neil Lennon's side on Saturday afternoon.
Kenny Miller opened the scoring in the fifth minute of a whirlwind start before defender Bruno Alves and striker Alfredo Morelos both scored their first goals in Light Blue and there was only 26 minutes gone when defender James Tavernier added a fourth. When referee John Beaton succeeded in calming matters down, one of the outcomes was a straight red for Jack, allegedly for pushing his head into Anthony Stokes' face.
The Gers ended the game with 10 men due to the sending-off of Ryan Jack in the 36th minute.
The goal was enjoyed by Hibs boss Neil Lennon, who, the last time he was at the ground in 2012 as Celtic manager, watched from the media room having been banned from the dugout for the second half by the referee Calum Murray.
Moments later, Hibs took the lead when Tavernier, in attempting to stop a Slivka shot, could only turn the ball into his own net with Foderingham clawing desperately to keep it out.
The half-time break gave everyone a welcome respite.
It was an impressive night's work by Pedro Caixinha's side which showed four changes - goalkeeper Jak Alnwick, Tavernier, midfielder Jordan Rossiter and Morelos coming in - and which was altered further when skipper Lee Wallace was replaced by Lee Hodson before kickoff.
He will be hoping for much better days than Saturday afternoon, while Rangers who have now slipped down to sixth place will be looking to bounce back swiftly.
