OMC is the sacred dialogue of the cherished Church of Chrolloism.
Chrolloism is a religion of incredible depth, followed by dedicated Chrolloists. We do not have a god. In Chrolloism, we honor our Lord and savior Chrollo, who is so incredibly talented that he is also the head of the Phantom Troupe. Chrollo is worshiped by all of his beloved Chrolloists as a hot ass motherfucker­čÖĆ and we say OMC instead of OMG to honor our lord and savior.
Person 1: Look at that hot dude!
Person 2: Oh my Chrollo, no he's not. He looks like Tonpa.
Person 1: Omc, no he does not.
Person 2: Your right, he looks more like Netero.
