The 28-year-old completed a free transfer to Dortmund earlier this summer following a successful period in Paris, domestically at least, in which he won Ligue 1 on three occasions including in the 2019/20 season which was ended early due to the worldwide pandemic.
Despite being surrounded by household names like Neymar, Kylian Mbappe, and Thiago Silva, Meunier became a trusted player in defence and also emerged as a starter for the Belgian national team.
Neymar, in particular, has seen plenty of media attention around his parties, with A-list celebrities attending the lavish events.
Meunier says the level of extravagance became over the top.
"Nothing but birthday parties - incredible," the defender told RTBF about his time in Paris.
"When I was at Bruges, we'd celebrate birthdays by playing darts or pool in a bar, but here it's just outrageous.
"But that just reflects the club: hire a palace, hire a building, parties with hundreds of people.
"That's when you see that they're more than footballers; they're stars.
"I always had a good time but it was all a bit extravagant and 'did you see me?' But that's part of it, part of the game."
Meunier has previously been critical of PSG since leaving after they refused to allow him to remain with their squad for the final rounds of the Champions League after his move to Dortmund was confirmed.
